Brock consults a therapist about the Delta Bi killings

Brock Chirino sits with his therapist, detailing the string of slasher attacks plaguing the Delta Bi fraternity after reckless pranks. He confesses the fear feels personal, tied to a vow of revenge from a sorority house mother trapped in a burning building. The session sets the stage for understanding the escalating violence.

The burning building sparks a vow of revenge

A sorority house mother survives a blaze and swears revenge on the Delta Bi brothers. Her vow foreshadows a brutal rampage that will reshape campus life. The event is told as a backstory that motivates the ensuing horror.

The rampage begins and the mother is confronted

The mother’s vendetta wipes out most of Delta Bi in a brutal spree. Brock and his friend Samzy mount a desperate counterattack and manage to kill the mother. The survivors realize the danger is not over yet, as the killer’s daughter continues the carnage.

The daughter dons the mother's face

The mother’s daughter seizes the opportunity, cuts off her mother’s face, and wears it as a mask. She adopts the name Motherface and steps into the killer’s role. The new villain begins a new cycle of violence.

Motherface launches a fresh terror campaign

Motherface erases more Delta Bi members with cold efficiency. The group tries to stay one step ahead as the body count rises. The attacks underscore the systematic nature of the new killer.

Brock ends Motherface with fire

In a white-hot act of vengeance, Brock sets Motherface on fire and ends her reign of terror. The killing of Motherface seems to bring a fragile respite to the survivors. Yet the memory of the horror lingers.

Therapist reveals she is the new Motherface

In a jarring twist, the therapist reveals she herself is the new Motherface and the sister of the original killer. She sinks her hands into Brock’s throat in a fatal flourish. The shock reframes the violence as a personal betrayal.

Brent joins Delta Bi to uncover the killer

Brent, Brock’s brother, pledges to uncover the killer and joins Delta Bi. He teams with a motley crew—Nedry, Samzy, Derek, Todd, Samantha, Turbeaux, ZQ, Sizzler, Turtleneck Bro, Flannel Bro, and Spike—to form a fragile alliance. Trust is tested as fear and bravado drive reckless choices.

A plane crash sets the group on a lakeside retreat

The prank-driven plan spirals toward disaster when a plane crash claims lives and pushes the survivors toward a lakeside retreat. The event deepens the group’s bonds and distrust in equal measure. The wreckage compounds the sense of doom hanging over Delta Bi.

Delta Bi heads to the lake house and Pepperstone is slain

Dean Pepperstone dispatches Delta Bi to the lake house, but Motherface ambushes them and Pepperstone is slain. She then cuts power to the property, turning the house into a stage for further carnage. The retreat becomes a trap as darkness closes in.

Paddy’s tragic backstory resurfaces and death follows

The raft salesman Paddy appears, his tragic flood backstory haunting the present as tragedy follows the group. His death is swift and grim, underscoring the cost of Delta Bi’s recklessness. The river’s memory becomes a motif that intensifies fear.

Attic revelations and a robot duplicate

Derek is murdered in an electrical-themed assault, and the attic becomes a theater for revelations as Samzy’s head is discovered. Brent realizes a robot duplicate may be involved in the deception. The survivors grapple with the nightmare logic behind the killings.

Sizzler, ZQ, and Sorrowous losses escalate

Motherface turns her gaze toward Sizzler and ZQ, tearing through the group with relentless force. Turbeaux is locked inside a room of dogs as a gun misfires in a final act of despair. Samantha is stabbed and cut in half as the group’s resolve fractures.

Brent’s resurrection and final showdown

The toll of the losses awakens a fierce strength within Brent, aided by Nedry’s death. He confronts Motherface one final time and finishes her for good. The price paid by the group is the erasure of innocence and the burden of consequences.
