Fifteen years later, on Christmas Eve, Billy, now 36, escapes from his cell and heads to his former home, now a sorority house for Delta Alpha Kappa at Clement University in New Hampshire. At the house, Clair Crosby, one of the sorority girls, is murdered in her bedroom by an unknown figure. Meanwhile, Megan Helms begins to hear noises and goes up to the attic to investigate. Upon finding Clair's corpse, Megan is attacked and killed by the same assailant. In the living room, the other sorority sisters, Kelli Presley, Melissa Kitt, Heather Fitzgerald, Dana Mathis and Lauren Hannon, along with their housemother Mrs. Mac, receive a threatening call from the killer. Clair's half-sister Leigh Colvin soon arrives, searching for her. Kelli's boyfriend Kyle Autry arrives as well but is kicked out when Kelli discovers Megan's sex video with him. When the power goes out, Dana goes to the main breaker under the house but encounters the figure in the crawlspace and is killed. When they realized Dana's ambush by the figure, the remaining sorority sisters and Leigh go outside to find her, only to find their fellow sister Eve Agnew decapitated in her car.
