The film opens with an older married couple peacefully sleeping in their bed, only to be startled awake by persistent knocks on their doors and windows. The husband bravely ventures downstairs to investigate the source of the commotion, but finds nothing amiss. Just as he settles back under the covers, a loud crash echoes from below, and he catches a glimpse of a shadowy figure ominously whispering, > "Little Pig." In a panic, he rushes back to his wife and hastily locks the door, but the intruders begin to shake and assault the door until it finally gives way. The scene transitions to a police officer entering the house, a harbinger of the chaos to follow.
The narrative swiftly shifts to a celebratory dinner at a restaurant, where four friends—Sharon, Jay, Wojciech, and Abigail—are honoring Abigail's birthday and impending departure. Later, the group heads back to Sharon's home. In a haunting moment, Sharon, who is pregnant, tries to reach her husband from the nursery, but the call abruptly drops. Meanwhile, a stranger visits a guest house to pitch a stereo to its occupant. Unfortunately, as he attempts to leave, the driveway gate malfunctions. Stepping out to resolve the issue, he finds his vehicle inexplicably powered down. Upon turning on his headlights, he is confronted by a menacing man standing in front of his truck and a woman lurking behind it, leading to his brutal abduction.
Wojciech, stepping outside for a cigarette, encounters a slumped figure beside the truck and approaches, asking if he’s okay. The man suddenly lunges at him, precipitating a frantic chase that leads Wojciech to a locked front door. The tension escalates, with blood spelling the word "Pig" ominously scrawled across the door.
As Sharon and Abigail converse in her bedroom, they are interrupted by Jay's screams emanating from the living room couch. Rushing to investigate, they make the chilling discovery that Jay has been brutally stabbed to death. The remaining friends take to hiding as the relentless intruders stalk them through the house. In a desperate bid for survival, Sharon and Wojciech are seized and dragged through the hallways, while Abigail makes a run for help. However, the occupant of the guesthouse, lost in his music with headphones on, fails to hear her frantic pleas. Tragically, one of the invaders captures Abigail and brings her back to the house.
The night takes a devastating turn as the remaining friends are methodically hunted down, experiencing sheer torment at the hands of the intruders. The film concludes with chilling interviews featuring Manson and some of the individuals involved in this harrowing story.
