“Chapter One: The Vanishing of Will Byers”

On November 6, 1983 in Hawkins, Indiana, a scientist is attacked by an unseen creature at a U.S. government laboratory. 12-year-old Will Byers encounters the creature and mysteriously vanishes while cycling home from a Dungeons & Dragons session with his friends Mike Wheeler, Dustin Henderson and Lucas Sinclair. The following day, Will’s single mother Joyce Byers reports his disappearance to the police chief Jim Hopper, who starts a search but assures Joyce that almost all missing children are quickly found. The lab’s director, Dr. Martin Brenner, investigates an organic substance oozing from the lab’s basement, claiming that “the girl” cannot have gone far. A nervous young girl wearing a hospital gown wanders into a local diner. The owner, Benny, finds a tattoo of “011” on her arm and learns that her name is Eleven. Brenner, monitoring the phone lines, sends agents to the diner after Benny calls social services. The agents kill Benny, but Eleven manages to escape using telekinetic abilities.

“Chapter Two: The Weirdo on Maple Street”

The boys bring Eleven to Mike’s house, where they disagree on what to do. Mike formulates a plan for Eleven to pretend to be a runaway and seek help from his mother, Karen. Eleven refuses, however, revealing that “bad men” are after her. Will’s brother Jonathan visits his estranged father Lonnie in Indianapolis to search for Will, but Lonnie rebuffs him. Hopper’s search party discovers a scrap of hospital gown near the lab. After recognizing Will in a photograph and demonstrating her telekinesis, Eleven convinces the boys to trust her, as they believe she can find Will. Using the Dungeons & Dragons board, Eleven indicates that Will is on the “Upside Down” side of the board and is being hunted by the “Demogorgon” (the creature). Mike’s sister Nancy and her friend Barbara ‘Barb’ Holland go to a party with Nancy’s boyfriend Steve Harrington. Searching for Will near Steve’s house, Jonathan secretly photographs the party.

“Chapter Three: Holly, Jolly”

Barb awakens in the Upside Down: a decaying, overgrown alternate dimension. She attempts to escape, but is attacked by the Demogorgon. Joyce believes Will is communicating through pulses in light bulbs. Hopper visits Hawkins Lab, and the staff permits him to view doctored security footage from the night Will vanished, leading Hopper to investigate Brenner and discovering his involvement with Project MKUltra and that a woman named Terry Ives alleged years earlier that Brenner took her daughter. Eleven recalls Brenner, whom she calls “Papa,” punishing her for refusing to hurt a cat telekinetically. Steve destroys Jonathan’s camera after discovering the photos from the party. Nancy later recovers a photo of Barb, simultaneously realizing that Barb is missing. Returning to Steve’s house to investigate, Nancy encounters the Demogorgon but manages to escape. Joyce paints an alphabetic board on her wall with Christmas lights, allowing Will to sign to her that he is “RIGHT HERE” and that she needs to “RUN” as the Demogorgon comes through the wall. Believing Eleven knows where Will is, the boys ask her to lead them to him. Eleven leads them, to their frustration, to Will’s house. From there they follow emergency vehicles to a nearby quarry just as Will’s body is recovered from the water.

“Chapter Four: The Body”

Joyce refuses to believe that the body found at the quarry is Will’s. Mike feels betrayed by Eleven until she proves that Will is still alive, channeling his voice through Mike’s walkie-talkie. The boys theorize that Eleven could use a ham radio at their school to communicate with Will. Nancy notices a figure behind Barb in Jonathan’s photo, which Jonathan realizes matches his mother’s description of the Demogorgon. Nancy tells the police about Barb’s disappearance. She later fights with Steve, who only cares about not getting in trouble with his father. Hopper has suspicions regarding the authenticity of the body found in the quarry when he learns that the usual coroner was sent home. Hopper confronts the state trooper who found it and beats him until he admits he was ordered to lie. The boys sneak Eleven into their school to use the radio, while Joyce hears Will’s voice through her living room wall. Tearing away the wallpaper, she sees him. Eleven uses the radio to channel Will talking to his mother. Hopper goes to the morgue and finds that the body is a fake, and, suspecting that Brenner is responsible, breaks into the lab.

“Chapter Five: The Flea and the Acrobat”

Hopper searches the lab before being knocked out by the lab’s guards. The boys ask their science teacher, Mr. Clarke, if it would be possible to travel between alternate dimensions, to which he answers that there could be a theoretical “gate” between dimensions. Hopper awakens at his house and finds a hidden microphone, realizing that Joyce was right the whole time. The boys follow their compasses, searching for a gate that could disrupt the Earth’s electromagnetic field. Eleven recalls memories of being placed in a sensory-deprivation tank to telepathically eavesdrop on a man speaking Russian; while listening, she came across the Demogorgon. Fearing another encounter with the Demogorgon, Eleven redirects the compasses. Lucas misinterprets this as an act of betrayal, leading Mike and Lucas to fight and Eleven to telekinetically fling Lucas away from Mike. While Dustin and Mike tend to the unconscious Lucas, Eleven runs off. Nancy and Jonathan formulate a plan to kill the Demogorgon. While searching in the woods, they encounter a wounded deer.

Becky explains that Terry was a Project MKUltra participant while unknowingly pregnant, and that Terry believes Brenner kidnapped her daughter Jane at birth due to her supposed telekinetic and telepathic abilities. Nancy and Jonathan stockpile weapons to kill the Demogorgon, theorizing that it is attracted by blood. Steve gets into a fistfight with Jonathan after calling Nancy a slut.

The group contact the kids, and everyone meets at the Byers’ house. Joyce and Hopper realize that Eleven is Jane Ives. The group ask Eleven to search for Will and Barb telepathically, but her earlier feats have weakened her. They break into the middle school and build a makeshift sensory-deprivation tank to amplify Eleven’s powers. Eleven finds Barb dead and Will alive, hiding in the Upside Down version of his backyard fort. Realizing that the gate is in the basement of the lab, Hopper and Joyce break into the lab and are apprehended by security guards.
