It’s 1985 in Hawkins, Indiana, and summer's heating up. School's out, there’s a brand new mall in town, and the Hawkins crew are on the cusp of adulthood. Romance blossoms and complicates the group’s dynamic, and they'll have to figure out how to grow up without growing apart.
Meanwhile, danger looms. When the town’s threatened by enemies old and new, Eleven and her friends are reminded that evil never ends; it evolves. Now they’ll have to band together to survive, and remember that friendship is always stronger than fear.
June 28, 1984...
One year later in Hawkins, Mike and Eleven are in an intimate relationship, something which Hopper is struggling to accept. The new Starcourt Mall has become the focal point of the town and the Party. Will begins to sense that something is wrong after a power outage but wants to believe that its nothing. Nancy and Jonathan have taken up internships at The Hawkins Post. Nancy is attempting to make a good impression but is unfortunately weighed down by her misogynistic superiors. Dustin returns home from summer camp where he claims to have met his new girlfriend named Suzie. Billy has become a lifeguard at the Hawkins Community Pool where he is admired by a group of middle-aged women, with Karen Wheeler among them. Hopper begins to turn to Joyce for advice for confronting Mike and Eleven about their relationship. Steve has begun working at an ice cream parlour called Scoops Ahoy at the mall, where he is attempting to flirt with women. His co-worker Robin Buckley pokes fun at his feeble attempts. Hopper asks Joyce out for dinner, but she claims to have plans. Dustin leads the Party to Hawkins’ tallest point, where they intend to place his new Cerebro to contact Suzie. Mike and Eleven ditch the Party early, claiming curfew. Rats are shown to be gathering at an abandoned steel works, where they all begin to explode into pieces. Billy asks Karen out on a date at a motel, which Karen agrees to. Suzie doesn’t respond to Dustin when he tries to contact her, leading Lucas and Max to believe that Suzie doesn’t exist. Joyce reflects on a happy memory with Bob as she watches TV on her own. The magnets on her fridge are shown to no longer function. While cleaning up, Nancy receives a call from an elderly woman named Doris Driscoll concerning a story about infected rats. Hopper confronts Mike and threatens him in an attempt to separate him from El. After many hours, Lucas, Max and Will decide to leave Dustin before he receives a mysterious Russian transmission. Karen is about to leave for her date before she has a change of heart. Billy is on his way before crashing his car in front of Brimborn Steelworks. He is then dragged into the steelworks down a flight of stairs by vines.
Billy is released from the Steel Works and experiences a vision in the Upside Down in which a group of clones of himself cryptically order him to build an army. Early the next day, Mike lies to Eleven over the phone concerning his absence by claiming that his nanna is extremely sick and that he can’t see her for the entire day, leaving her confused. Hopper, seeing that his plan worked, proceeds to visit Joyce at work once again to gleefully tell her this and to take another crack at asking her out, which succeeds this time. Nancy gets out of work and brings Jonathan along on her secret diseased rats case. Dustin reunites with Steve and asks him for help in translating the Russian transmission. Eleven pays Max a visit to talk about Mike. Upon hearing her story, Max tells her to ignore his calls and threaten to dump him if he doesn’t explain himself. Meanwhile, Mike turns to Lucas for help. As Lucas is reassuring Mike, Max takes Eleven out to ‘have some fun’. At the pool, a visibly disorientated Billy dismisses Karen's apology. The sun appears to be viciously attacking his senses. Back at Scoops Ahoy, Robin walks in on Steve and Dustin's translation attempt and offers to help out of boredom. Nancy and Jonathan arrive at Mrs. Driscoll’s house to inspect and ask questions about the ‘diseased‘ rats that have been devouring her fertiliser. She suspects that they have rabies. Protests are shown to be taking place at city hall while Hopper takes a meeting with Mayor Larry Kline, who orders him to get rid of them. Max and El go shopping at the mall. Mike, Lucas and Will are also shopping for a present for El. Joyce becomes suspicious of the failing magnets and decides to go ask Scott Clarke about it. Nancy finds a lead. Driscoll's rat explodes after they leave. Billy’s state decreases, and leads him to attack and kidnap his co-worker Heather . El and Max are on a shopping spree while the boys struggle to find a suitable gift. Eleven confronts Mike for lying and dumps him. Hopper arrives at his dinner with Joyce, but she doesn't show. Scott gives a theoretical reason for why Joyce’s magnets have stopped working, which involves an extremely expensive and high-powered machine that could be running nearby. Robin finishes the translation: “The week is long, the silver car feeds, when blue meets yellow in the west.” They also discover that the transmission was made there in the Mall. Hopper drunkenly leaves the restaurant after Joyce doesn’t show. Billy brings a gagged Heather to the steel works, where she is confronted by a fleshy creature.
At Hopper‘s cabin, Eleven uses her powers to eavesdrop on the boys. El proceeds to spy on Billy next, coincidentally at the same time he was delivering Heather to the creature. What El witnesses disturbs her to an extreme level. The next day, Will is in a festive mood as he declares a ‘day without girls’ at the Wheeler house, a day that entails a game of Dungeons & Dragons. Joyce pays a disgruntled Hopper a visit in order to fill him in with her suspicions about the magnets and how they could be connected to the lab, though he dismisses her instantly. Despite this, Joyce forces him to investigate the lab with her. El and Max investigate Billy’s room, where they find a bloody lifeguard’s whistle. Robin is continuing the translation while Steve and Dustin comb the mall for Russian spies. Back at the Wheeler house, Mike and Lucas are showing little to no interest in Will’s campaign, which leads to him giving up and storming out of the house. Mike tries to make amends, but Will dismisses him and bikes out in the rain. El and Max go to the pool to return the whistle and kit they found. They discover that the owner, Heather, is not present. El finds a photo of her and uses it to find her in the void, where she is found in a tub of ice, begging for help. Hopper and Joyce arrive at Hawkins National Laboratory. Dustin spots what he believes to be an “Evil Russian”, who turns out to simply be a Jazzercise instructor. Robin finally figures out the message. Nancy’s story is ridiculed by her boss Tom Holloway and their colleagues. Even more determined, she convinces Jonathan to come with her back to Mrs. Driscoll’s house to find more evidence to present to Tom. Joyce and Hopper find nothing, leading Joyce to believe that she is going crazy. Hopper reassures her by feeling the exact same way. He also reveals that he is aware of Joyce‘s plan to leave Hawkins and attempts to softly reason her against it. They are interrupted by the sound of one's presence in the lab. Mike and Lucas follow Will back to his house to apologise, but he isn‘t there. He is sitting in Castle Byers where he emotionally reminisces of old times, which leads to him destroying the fort in tears and anguish. Nancy and Jonathan arrive at Mrs Driscoll’s house, only to find her eating fertiliser while making monstrous noises. Steve, Robin and Dustin witness a transgression between what they assume are Russians, which involved the moving of boxes into a secret room guarded by armed men. They accidentally create a loud sound, which alerts the Russians to their presence. The three of them make it out of there before being found. At the lab, Hopper is searching for the source of the noise, which introduces itself by surprise-attacking him and beating him to the ground before escaping on a motorbike. El and Max arrive at Heather’s house, only to find her and her family (her parents Tom and Janet) having dinner with Billy. Heather appears to be well, and the girls make their way out. Billy recognises El as being the girl that shut the Gate the year previously through the Mind Flayer’s memories. Right at that moment, Will begins to sense the Mind Flayer’s presence again, which leads him believe that the Mind Flayer has returned. At Heather‘s house, Janet passes out. While Tom is distracted, Heather hits him across the head with a wine bottle and drugs him.
While Max seems convinced that everything is fine, El still feels uneasy. At the same time, Mrs. Driscoll is taken to hospital while screaming “I have to go back!” repeatedly. Tom And Janet wake up in Brimborn Steelworks where they become under the control of the Mind Flayer. Hopper wakes up the next morning in his cabin, where Joyce brought him. They try to identify who the attacker was, and Joyce notes that he didn’t have a car. Mike, Lucas and Will try to gather the whole party together, though they were unsuccessful in contacting Dustin, whom is currently deciding with Steve and Robin how they are going to get in to the secret room in the mall. Tom Holloway fires Nancy and Jonathan. El and Max reunite with the boys as Will is explaining his suspicions and theories about the Mind Flayer. Based on last year’s events, he believes that it has most likely chosen a new host. Arriving at city hall, Hopper confronts Mayor Kline about his attacker. When things turn violent, Kline reveals that the man works for Starcourt Mall and is bribing him for properties throughout East Hawkins. Hopper demands to see records of this. Jonathan shows disdain towards Nancy for getting them fired. The Party draw their attention to Billy and his odd behaviour. They form a plan involving a sauna that will prove whether or not he is a host. At Scoops Ahoy, a series of persuasion and bribes convince Erica Sinclair into assisting them. Kline leads Hopper and Joyce to a safe in his bedroom, which provides a variety of addresses to bought properties. Joyce suspects that the machine Scott Clarke was talking about is located at one of these properties. Karen encourages Nancy to keep digging. While the Party prepares for their plan, attempts at making amends for recent conflict fail. At the mall, Robin’s plan works perfectly, as Erica was able to climb her way through to the room, allowing the other three inside. Back to the pool, Mike lures Billy to the sauna, where Eleven locks him in. Will turns up the heat, and they wait. Nancy arrives at the hospital to see Mrs. Driscoll in order to look through her records. At the mall, Steve begins to open up the boxes, which they find are filled with crates of green radioactive material. The walls begin to shake, and before they can leave, they discover that they are in an elevator, which begins to go down at a rapid speed. Mrs. Driscoll’s heart rate is beginning to increase as Nancy continues to write notes. At the pool, Eleven engages in a confrontation with Billy as the Mind Flayer takes hold of him and proceeds to attack the Party. As this is occurring, the lights in Mrs. Driscoll’s hospital room begin to flicker as she becomes covered in black veins. Eleven nearly kills Billy after throwing him through a brick wall, weakening her. Billy retreats in agony. Heather tends to Billy at the steel works. It’s revealed that they have infected at least 20 of Hawkins’ residence.
Steve, Dustin, Robin and Erica are trapped in the elevator. Hopper and Joyce come across a farm as one of the listed locations, where they find two Russians in an underground room. They attempt to question them before Russian agent Grigori arrives. Him and Hopper have a showdown, which ends with him and Joyce escaping with one of the Russians in captivity. Nancy calls Jonathan from the hospital early next morning, demanding to know where Will is. She claims that he may be in danger. Outside the cabin, Hopper is trying to get his broken down truck working again as Joyce tries to question the Russian, who is a scientist by the name of Alexei. Hopper’s efforts end in the engine exploding, leaving the three of them no choice but to walk aimlessly through the woods. Their objective is to go to Illinois, where an “acquaintance” of Hopper lives who can speak Russian. Eleven hears some of this while spying on him in the Void, and relays it to the rest of the Party, who have regrouped at the Wheeler house. They are completely unsure of what their next move should be. They are soon joined by Nancy and Jonathan, who are looking for Will. Beneath the Starcourt Mall, Dustin tries to contact the ground level through his walkie-talkie, but to no avail. Finally, the elevator doors are opened by a pair of Russian soldiers, who are there to collect the crates. The kids make their way out as the doors are closing. They then begin to set out through a long tunnel passageway. Back at the Wheeler house, Nancy begins to connect her story with what the Party has discovered. This leads to them believing that Mrs. Driscoll, Tom and Heather Holloway are all Flayed along with Billy. They proceed to investigate the Holloway house. Grigori finds Hopper’s truck, where he finds footprints. Hopper, Joyce and Alexei find a gas station, where they hijack someone’s car. While walking through the tunnel, Robin begins to question why the Russians have so much interest in Hawkins of all places. Steve and Dustin have their own suspicions that they choose to not share with the other two. The Holloway house is found to be extremely cold and vacant. They also find many chemicals. They concur that the ‘flaying’ is happening at a specific location. Will brings up the idea of having Mrs. Driscoll lead them there from the hospital. Grigori interrogates the gas station clerk as Hopper, Joyce and Alexei arrive at the residence of Murray Bauman. Steve, Dustin, Robin and Erica stumble upon a room full of soldiers. They manage to make it to the comms room, where Steve manages to takes out one soldier. They grab his key card, but before they leave they decide to inspect an odd-looking room nearby. They discover that the Russians are trying to create a Gate to the Upside Down. The Party arrives at the hospital, but only Nancy and Jonathan are allowed to visit her. While they wait, Lucas encourages Mike to try to repair his relationship with Eleven. Nancy and Jonathan make amends for their fight on their way up. They find that Mrs. Driscoll is not there. They instead find Tom Holloway and Bruce Lowe, who has also been Flayed. They proceed to attack them. Mike compliments El’s dress as he offers her M&Ms. Meanwhile, Nancy And Jonathan are racing through the hospital. They eventually get separated, with Bruce going after Nancy and Tom chasing Jonathan. After a series of beat downs and chases, both Tom and Bruce are defeated. Their two corpses proceed to melt into fleshy goo. The two piles move by themselves before they reach each other and collude, becoming one big fleshy monster.
Steve, Dustin, Robin and Erica are found by the Russians. Steve and Robin give the other two time to hide before they‘re captured. Back at the hospital, Will senses the Mind Flayer‘s presence as the lights begin to flicker, alerting the others. Upstairs, the fleshy monster chases after Nancy, who locks herself in a separate room. The monster is able to bypass the room very quickly and is about to finish her off before Eleven bursts open the door with the others and uses her powers to throw the monster out of the building. It proceeds to retreat through a drain. The next day, Mayor Kline’s Fun Fair begins to take shape. Kline meets with Grigori, who gives him one day to find Hopper. At Murray’s Warehouse, Alexei is refusing to talk without his specific demands, which drives Hopper up a wall. Over time, Alexei realizes that his best bet is to side with the Americans rather than his comrades. Dustin fills Erica in on the events of the last two years as they journey through air ducts, which leads to an argument over whether or not Erica is a nerd. A Russian officer, Ozerov, is convinced that Steve and Robin are working for a higher power. Steve tries to tell him otherwise, but he doesn’t believe him and proceeds to have tortured until he talks. Nancy, Jonathan and the Party have regrouped at Hopper’s cabin, where El is searching for members of the Flayed through the Void. Mike and Max argue over El’s rights before she tells them that she found Billy. At Murray’s Warehouse, Alexei, through Murray’s translation, begins to communicate to Hopper and Joyce what him and his comrades have been doing. Joyce tries to call her kids while Hopper reassures Alexei that he will get him to his Key, though Alexei claims that access to the Key is impossible. Dustin and Erica commandeer a cart and a taser as Robin screams for help. She and Steve attempt to free themselves of their binds, which fails. They share a tender moment before Ozerov comes back with Dr. Zharkov, who infects a needle into Steve’s neck. Billy is simply sitting in his room. The Party believes he is setting a trap, so Eleven comes up with a new idea. When she tries to reach him, she succeeds in accessing his memories, where she witnesses his child self sharing a moment with his mother. Hopper sends a distress call to Dr. Owens before him, Joyce, Alexei and Murray head back to Hawkins. Ozerov interrogates a now lucid Steve, who tells him about Dustin and claims that he’s ‘long gone’ right before an alarm goes off, distracting Ozerov while Dustin and Erica enter and take down Dr. Zharkov with the taser. Eleven continues to see more of the abuse Billy suffered at the hands of his father. She sees more and more before she finally reaches Brimborn Steel Works. She seemingly exits the Void, only to find that she is alone. Billy enters the cabin, claiming that he knows where she is, and that everything him and the rest of the Flayed have been doing has been for her. He claims that he is going to end her, her friends, and then everyone. Eleven leaves the Void in shock and despair. The Flayed gather at the steel works, where they all melt into goo to become one massive spider-like monster.

The Duffers stated they wanted to start the third season with a clean slate, intentionally ending the previous season with few cliffhangers, so that they can focus on creating a better story with more freedom. They also hinted that several ideas that didn't make it in the second season may be used. By mid-November, the season was in the early stages of development. In January, producer Shawn Levy revealed that all of the characters' story lines have already been planned out, and that the season will have eight or nine episodes, depending on the "amount of story that excites them." He also confirmed that Will Byers will not be the main victim this season, and that the friendship between Dustin Henderson and Steve Harrington will continue. In February, it was announced the season will have eight episodes.
In March, Levy also revealed that Season 3 would take place during the summer of 1985, a year after the former season and added that the relationship between Mike and Eleven as well as Max and Lucas will continue. Moreover, he promised that Steve Harrington will have a much larger role.
In an interview, Noah Schnapp told that the third season will be very unique as it will be combining both the darker and lighter elements of the previous two seasons. Additionally, he confirmed that Erica will have her own story-line with "someone from the cast". At Stranger Con, he also hinted the possibility of seeing more D&D scenes this season.
In July, Levy gave more information on the season's tone, saying it is going to "darker" places while also mentioning it has "heart and humor." David Harbour mentioned that the season will be taking more risks and hinted at the inspiration from several films released during 1985. Harbour later revealed that one such film is the 1985 comedy film Fletch. In addition, he described his character, Hopper, as being almost a combination of the previous versions of the character from the two prior seasons.
In late July, Levy stated the season will be the "most ambitious" season yet, with inspirations being John Carpenter and other '80s horror directors. Later, he also clarified his previous statement regarding the season's tone, saying that there will still be "plenty of summer fun." According to Finn Wolfhard and Millie Bobby Brown, the season will be the "Summer of Love".
In late May, the Duffer brothers revealed in an interview with "Entertainment Weekly" that the Mind Flayer was still alive in the Upside Down and would find another way into Hawkins. They also teased that the season will explore the theme of change among the kids who are experiencing their transition period.
In mid-June, speaking to Empire, Noah Schnapp revealed that the Mind Flayer will still have a presence on Will in the season. Finn Wolfhard also reiterated that the season will combine the fun aspects of Season 1 and the horror aspects of Season 2.
Borrowing inspirations from the movies of David Cronenberg, John Carpenter and George Romero, the Duffer Brothers sought out to create a darker premise for the third season. They also wanted to pay homage to many classic pop cultural films of the mid 80's. Speaking to "Entertainment Weekly", they revealed the names of some such films, which include Fast Times at Ridgemont High, Romancing the Stone, Midnight Run, Indiana Jones and Jurassic Park.
While discussing inspirations for season three with the cast and crew, Bodysnatchers came up the most with Philip Kaufman's Invasion of the Bodysnatchers being one of them. According to actor Charlie Heaton, E.T. and The Goonies didn’t so much inspire this season as much as scarier films like Sam Raimi's Evil Dead.
On March 2, Variety announced that Priah Ferguson, who portrays Erica Sinclair, had been upped to a recurring role. Her storyline for the season was described as "No longer content with sitting on the sidelines, Erica finds herself on a wild mission to save Hawkins from a dangerous new threat." They also revealed that Maya Hawke will be joining the cast as Robin, an "'alternative girl' bored with her mundane day job. She seeks excitement in her life and gets more than she bargained for when she uncovers a dark secret in Hawkins, Ind."
In April, it was announced that Cary Elwes, best known for his performance as Westley from The Princess Bride, had been cast as Mayor Kline, who is described as “handsome, slick, and sleazy. He is your classic ’80s politician — more concerned with his own image than with the people of the small town he governs.” Additionally, Jake Busey was revealed to have been cast as Bruce, a journalist for The Hawkins Post “with questionable morals and a sick sense of humor.”
In late September, casting director Carmen Cuba revealed that she and the Duffers were still searching for new additions to the cast. Cuba stated they had a challenging storyline that requires them to continue searching for new talent.
According to actor David Harbour, production was scheduled to begin in April 2018. TVLine additionally reported that production was slated to begin in mid-April. Production officially began on April 20, and a production teaser was released on April 27, showing the cast members at the table read.
Filming for the season officially began April 23.
According to executive producer Iian Paterson, the season was filmed almost entirely on location.
Aside from filming at EUE Screen Gems Studios in Atlanta, the crew shot scenes at a public swimming pool located in South Bend Park, Georgia for three days starting from May 5. In preparation for filming, a portion of Gwinnett Place Mall, located in Duluth, Georgia, was refurbished to resemble an '80s-era mall, including several outlets popular during the time. According to casting calls looking for mall patrons and employees, filming at the location took place May 14 - 18. Filming also took place in many other locations including in Stone Mountain on June 18 and 20, and the Serenbe Farms of Chattahoochee Hills on August 1-2.
According to cinematographer Tim Ives, filming for the first two episodes had completed on May 25. The third and fourth episodes had finished filming in mid-July. Filming for the fifth and sixth episodes had concluded in early-September.
On September 27, actress Millie Bobby Brown was observed filming a scene from the upcoming season on a beach in Malibu, California.
Filming officially wrapped on November 13.
For filming the episodes, Tim Ives upgraded to the 8K Red Monstro (Brain) camera and decided to use the Leica Thalia lenses.
Netflix's VP of original programming, Cindy Holland, gave the reason for the show's delayed release during the Television Critics Association press tour. She explained that the Duffers and Shawn Levy wanted to deliver something "bigger and better" than the previous season, later noting that the season's special effects will additionally take more time. Holland assured that the season will be fantastic and worth the wait.
