On Halloween night 1965, a fallen
Catholic priest named Zachary Malius murders seven fraternity
pledges from Winfield College who apparently broke into his family's crypt and enacted an
occult initiation ritual. After being confronted by his peer, Father Cane, who believed Malius was
possessed, Malius was incarcerated in an insane asylum for his crimes; Henry Collins, a pledge that year, was the only survivor. In 1991, during
pledge week, the university students are preparing for
hell night. Fraternity member Eric Collins, the son of Henry, is suggested by his fraternity brother Ned to have the new pledges break into the local insane asylum and photograph Malius as their initiation ritual. Eric later mentions the prospect to his father over the phone, which causes Henry to cut their call short. Later that afternoon, Eric finds his girlfriend Liz having sex with his younger brother, Sonny, in a hotel room. To punish him, Eric appoints Sonny and fellow pledge Ralph to photograph Malius as their initiation. Sonny and Ralph break into the asylum and find Malius's cell sequestered in the basement, but when Ralph attempts to take a photo, Malius attacks and kills him. Sonny flees on his motorcycle while Malius murders a nurse orderly before escaping. Meanwhile, Liz arrives at the party with her friend, Susan, and attempts to apologize to Eric at the party, but is rebuffed. She finds Ned Bara, a nerdy fraternity member, downstairs, and he inadvertently reveals Sonny's initiation ritual to her. Concerned when Sonny fails to return by midnight, Liz stops by the local church and seeks advice from the priest, Father Cane. When she explains Sonny's initiation assignment, Cane panics and urges her to go into hiding. Back at the fraternity house, the party begins to phase out, and Eric initiates sex with a
Kappa Sigma sorority sister, but she stops him when he cannot find a
condom. She attempts to leave the fraternity house, but is subsequently murdered in her car by Malius, who drives an
ice axe through her head. Malius subsequently kills several partygoers in the house. Meanwhile, Henry, arrives in town and visits the church, where he finds Cane's body hanging posed as the
Cross of Saint Peter above the altar. Liz returns to the fraternity shortly after, finding it apparently empty. Throughout the house, she discovers multiple corpses before being confronted by Malius, but she evades him. Eric and Sonny subsequently arrive, and the three band together with Ned, who has
closed-circuit monitors of the house in his room. Communicating to Ned via a walkie-talkie, Eric, Sonny, and Liz locate Susan, who is decapitated in the attic. Malius stalks them through the house, before Eric shoots him with a speargun, and he falls out a window. Henry arrives moments later, and confesses that he and Malius conspired together in 1963 to recreate a Satanic ritual, in which Henry made a
pact with the devil that yielded him power and wealth. Malius, unfazed, murders Ned downstairs before impaling Henry with the ice axe through the door, killing him. Eric, Sonny, and Liz find a book in
Latin inside Henry's satchel detailing the ritual he performed with Malius twenty-five years earlier. Eric and Liz run to the cemetery and attempt to recreate the ritual in the Malius crypt. Malius arrives and stabs Eric through the chin, but is stopped from killing him when Sonny arrives moments later. Sonny and Liz complete the ritual, but Malius takes Sonny with him to
hell. The police arrive at the cemetery shortly after, and Liz leaves with Eric in an ambulance. As she assures Eric everything is going to be alright, the ambulance driver turns around and reveals himself to be Malius. ==Cast==
