Sorority House Massacre

As a child, Beth's brother Bobby kills their entire family and tries to kill her. He is captured and committed to a mental institution. The trauma leaves Beth to be raised by a new family.

Years later, Beth enrolls in college and becomes part of a sorority. The new environment offers normalcy, but she remains haunted by flashes of a past she can't fully recall. The sense of danger lingers as she settles in.

Beth experiences a memory lapse, not realizing the sorority house is her childhood home. Small, unsettling memories begin to surface, hinting at a past she can't fully place. The recollections grow stronger just as danger approaches.

Bobby senses Beth's presence and escapes from the asylum, propelled by unfinished business. He moves toward Beth and starts preparing for a confrontation. The threat against the sorority becomes imminent.

Hunting for his target, Bobby stops at a hardware shop to arm himself and ends up killing the elderly owner. The brutal murder confirms his lethal intent and escalates the danger to Beth. The killer is now in motion toward the sorority house.

Most sisters leave for the weekend, leaving Beth, Linda, Sara, and Tracy in the house as Craig, Andy, and John arrive as visitors. The uneasy mood thickens as an old family tragedy is repeatedly referenced. John starts telling the tale of Beth's murders, unsettling her.

Beth dreams of Bobby and wakes terrified. She recalls Bobby hiding a knife in the fireplace, and the group discovers the weapon, which heightens their fear and sense of vulnerability. The danger feels close at hand.

In the escalating terror, Andy tries to leave but is confronted by Bobby and stabbed to death. The group realizes the killer has infiltrated their safe space and is willing to kill at will.

Tracy and Craig head outside to the tipi they built, where Bobby attacks and destroys the structure. Tracy is killed while they attempt to escape; Craig runs back inside to warn Linda and Sara.

Linda and Sara try to call the police but find the lines cut. They rush to warn Beth and John, who have fallen asleep. Bobby approaches and murders John, intensifying the siege inside the house.

The survivors barricade themselves in a room as Bobby stalks them. Craig escapes out a window and steadies a safety ladder for Linda to climb down. Bobby lunges and stabs Craig to death before he can help more.

Linda makes it out through the window as the ladder is removed, causing Bobby to fall and vanish from sight. The group hopes they are safe, but fear he may still be alive and returns inside.

The group flees again and encounter Bobby, who relentlessly stabs Sara. Meanwhile, Bobby's search party heads toward their old family house to inform the police of his whereabouts and secure help.

Beth and Linda retreat to the basement, where Beth confronts the full horror of her past. Bobby attacks again; Linda defends herself with a shovel but is stabbed. Beth ultimately overpowers Bobby and stabs him in the neck, ending his threat. Police arrive as Beth is taken to the hospital, where she continues to have nightmares about her brother.
