PlotIn a flashback, Eleven awakens to find herself in the Upside Down, just after disintegrating the Demogorgon. Exhausted and frightened at first, she desperately searches for Mike. Upon searching, she discovers a portal the Demogorgon had created. By using her powers to enlarge it, she escapes through it. She makes her way to Mike's house where she sees him being talked to by government personnel telling him that her stories were not true. Mike doesn't believe that but as he turns away, he catches a glimpse of Eleven through the window, making the agents suspect she's there. Realizing that she is in danger, Eleven runs off into the forest to hide.
In the present, Hopper makes breakfast for him and Eleven as she walks in, dressed as a ghost, and asks if she can go trick-or-treating for Halloween. She believes that she will not be noticed with the sheet over her, but Hopper refuses because it is too dangerous. Although disappointed, Eleven agrees to his offer of having a night in together with candy and scary movies, terming it "halfway happy".
Hopper then goes out to work, where he learns that more pumpkin farmers in Hawkins have found their crops rotting mysteriously, impelling him to inspect the affected regions.
At the cabin, Eleven is watching TV when she hears a noise coming from outside. Going over to the window to investigate, she sees a squirrel, causing her to remember an occasion where she was approached by a hunter as she was cooking a squirrel she had killed. After rendering the hunter unconscious, she stole his coat and hat for warmth.
Dustin and Lucas invite Max to go trick-or-treating with them, Mike and Will. She doesn't initially accept. When school ends, Max goes home with her stepbrother Billy who attempts to run over Mike, Lucas and Dustin. Max grabs the steering wheel so they miss the boys.
Nancy and Steve attend a Halloween party where Nancy gets drunk and tells Steve that she does not love him which causes him to leave. Jonathan takes her back home. The boys go trick-or-treating dressed as the Ghostbusters, and Max ends up joining them. Mike, who was unaware of Dustin and Lucas' invitation, is disgusted as he thinks she is ruining the best night of the year. Falling behind, Will has another episode experiencing himself back in the Upside Down as a shadowy monster in the sky attempts to catch him. Mike takes Will back to the Wheelers' basement, where Will explains that he felt he was trapped in between the real life and the Upside Down. He also requests Mike not to inform anyone about it. Mike tells that Eleven would have understood it as she always did.
Back at the cabin, Hopper returns to Eleven and attempts to convince her to open the door, apologizing her for being late again. Instead, Eleven tries to contact Mike through the Void and watches him at the pillow fort. Mike reveals that it has been 353 days since she disappeared and he misses her. He has also been attempting to contact her daily ever since. But as Eleven reaches out to contact him, Mike, unaware that she was actually there, leaves. Unable to communicate with him, Eleven weeps in tears.
Dustin returns home when he hears a noise in the garbage bin, he opens it to find something inside.
