S4E4 · Chapter Four: Dear Billy

Complete story — includes the ending

Joyce and Murray deliver the ransom payment to Antonov's contact, Yuri, but he drugs them and plans to hand them (and Hopper and Antonov) over to the Russians for a larger profit. Hopper escapes from the prison camp but is soon recaptured. Jonathan, Mike, and Will prepare to escape from Wallace and Harmon, agents sent by Owens to watch them, but armed soldiers attack the house. They escape with the help of Jonathan's friend Argyle, bringing the wounded Harmon with them. Nancy and Robin interview the imprisoned Victor Creel, who recounts how his family was tormented and killed by supernatural forces while he was being arrested for their murders. Max, fearing that Vecna is about to kill her, writes letters to her friends and family and goes to the cemetery to read Billy's letter at his gravestone. She is soon possessed by Vecna and finds herself at an altar within her mind. Steve, Dustin, and Lucas learn from Nancy and Robin that playing music can break Vecna's spell, and they put Max's favorite song, " Running Up That Hill," on a cassette tape. This opens a portal through which Max narrowly escapes Vecna's control.
