Killer Party

Mrs. Henshaw visits the Pratt House garden and warns Allan's spirit to leave the students alone. She then enters the house, where an unseen assailant bludgeons her to death. Her murder foreshadows the danger awaiting the pledges during hell week.

Vivia, Jennifer, and Phoebe sneak into a nearby boys' fraternity to steal clothing for their hazing ritual. The break-in sets the stage for their initiation and the prank they plan to pull. Tension builds as the group prepares for the night ahead.

Inside the fraternity, Jennifer is confronted by Blake, who quickly shows romantic interest in her. The encounter adds a personal complication to the initiation and foreshadows later tensions. The moment intensifies the mood at the frathouse.

The trio arrives at Pratt House for their hazing ritual, which includes holding raw eggs in their mouths and eerie lights flickering. Glasses fly off a table, and Vivia is bound to a guillotine, only to reveal the beheading as an elaborate dummy prank. The fake spectacle masks a real sense of dread.

The following morning, Martin drives the women to the sorority, and all three are accepted. Vivia learns that her prank was the sole reason for her acceptance, a fact that unsettles her as she confronts the consequences of their stunt.

Veronica, the sorority's mean leader, orders Vivia to recreate the prank during the upcoming April Fool's Day masquerade at Pratt House. The demand raises the stakes and ties the prank to the house's dark past. The pressure mounts as the event approaches.

At a university Greek society meeting, Professor Zito recollects the hazing ritual 22 years earlier that resulted in Allan's death by guillotine. The memory casts a long shadow over current events and foreshadows the peril to come. The atmosphere grows ominous as old wounds resurface.

Jennifer, Phoebe, and Vivia set up the prank in Pratt House, and Jennifer reveals research claiming Allan involved in occult activities and linked disappearances. The group's plans deepen the house's sinister aura and hint at supernatural forces at work. The atmosphere turns more perilous as they proceed.

Professor Zito inspects Pratt House and is electrocuted by an unseen assailant in the basement. The death confirms that someone or something is actively targeting the investigators and participants. The danger intensifies as the house's secrets begin to unfold violently.

During Veronica's toast, Jennifer is dragged into the basement by a hidden cord while guests watch in horror. The trio briefly considers continuing the stunt, but Jennifer is suddenly possessed and returns upstairs in silence, signaling a shift from prank to peril.

Pam is killed with a trident by a diver-suit wearing assailant; Veronica is beaten to death with a hammer, and Albert is killed using the guillotine. A wave of swift murders follows, revealing the killer's merciless reach within Pratt House. Blake is later found dead in the bathtub, heightening the horror.

Vivia and Phoebe discover the dismembered Virgil in the refrigerator and the drowned corpse of Blake in the bathtub, among other chilling signs of the night's carnage. The surviving pledges scramble to understand what they are facing and how to escape. The atmosphere tightens with fear as the true danger becomes clearer.

Jennifer, now possessed by Allan, pursues Vivia and Phoebe as they attempt to flee upstairs. The stairs collapse under pressure, breaking Vivia's legs, and Phoebe uses a broken board to impale Jennifer, seemingly ending the immediate threat. However, Allan's spirit appears to endure, hinting at a lingering menace.

Police arrive and whisk the surviving women away in an ambulance, while Vivia pleads not to be left alone with the possessed Phoebe. The ambulance drives off into the night as Vivia screams, leaving a sense of unresolved horror and the possibility that the curse persists.
