Peter decides to build a multiplex to top Joe's new theater, but comes across an Indian skull in his backyard. As a result, a poltergeist haunts the Griffins' house and spirits drag Stewie away to the other side, followed by even stranger events.

In a spoof of the movie Poltergeist, the Smith home is haunted by Francine's unsatisfied sexual drive, so it is up to Roger - as medium Ruby Zeldastein - to eliminate the ghost. In the mean time, Hayley introduces the family to her younger boyfriend, Mauricio.

The detectives investigate the link between Rosie Larsen and casino camera footage; Mitch Larsen learns that her jailed husband, Stan, has drained their bank account; and the Richmond campaign gets new life as the mayor's takes a hit.

In 1983, in a US Department of Energy laboratory in the town of Hawkins, Indiana, a scientist is attacked by an unseen creature. 12-year-old Will Byers vanishes after encountering the creature while riding his bicycle home from a Dungeons & Dragons session with his friends. The next day, a young girl with a shaved head, wearing a hospital gown, steals food from a local diner. The owner, Benny (Chris Sullivan), takes pity on her and feeds her before calling social services. A woman posing as a social worker arrives and shoots Benny. Armed men search the diner for the girl, but she escapes. Joyce, Will's mother, believes she hears Will's voice on a distorted phone call, but her phone short circuits. Will's friends Lucas, Mike, and Dustin find the girl in the woods as they search for Will.

It is the day before the Harvest Festival and trouble seems to be brewing. A local Wamapoke is upset because the Festival grounds are on top of an Indian burial site and suggests that if the Festival is not moved it will be cursed. To make matters worse, Li'l Sebastian, a mini-horse who is the pride of Pawnee and an attraction at the Festival, goes missing on Tom's watch and reporter Joan Callamezzo is determined to humiliate Leslie with the Festival's failure. April tells Andy she loves him, but is less-than-pleased with his response and Ann, working as a Festival medic, is hit on by an obnoxious patient. With his recent media scandal still unforgotten, Ben feels that he is responsible for the curse and abandons the Festival.

Stan learns his new neighbors are Iranian and immediately suspects that they are terrorists. Meanwhile, Roger tries to discover any hidden alien powers he may have while Steve is left at the mercy of the Scout Rangers.
