Wearing dark suits, Lomax, Steele and Billy ride an elevator up to a hotel room and pick the lock. The place is empty except for a doll, a woman’s wig, and a silk negligee. They wait for Aubrey, the occupant, to return. When Aubrey shows up with boyfriend Harold, Steele beats Aubrey and Lomax stuffs the burning end of his cigar into Aubrey’s mouth. Harold is sickened, and Billy is also uncomfortable with the level of violence. When Aubrey dies from the beating, Steele turns his attention to Harold, who panics and jumps out the window. The three men drive out of town to "disappear." When Lomax asks Billy what is bothering him, Billy replies they should not have killed Aubrey. Meanwhile, at a farmhouse, Lisa, a teenager, is taking care of her wheelchair-bound grandfather. She pushes him in front of a television set, then goes to the refrigerator. Lomax, Steele and Billy enter a country convenience store. Steele takes a bite of an apple, spits it out, and hurls it at the female clerk. Then he orders the clerk to take off her shirt. When she removes her blouse, he drags her to the back of the store, puts an apple on her head and shoots a bottle of ketchup on the shelf above her, splattering the red paste into her hair and face. Meanwhile, in a hen house, Lisa picks up a chicken, strokes it like a baby, then chops off its head with a hand axe. In the house, Lisa puts the chicken in the kitchen sink to drain, then carries a tray with a bowl of raw eggs upstairs to her grandfather. Lisa feeds him the eggs, then gives his face and shoulders a sponge bath and begins to lather his beard, but she changes her mind. Hearing an engine in the yard below, Lisa peeks through the curtains and sees Lomax get out of the car. As Lomax knocks on the door, Steele glimpses Lisa in the upstairs window. Lomax slips through the back door into the kitchen, where he sees the headless chicken in the sink. He lets Steele in through the front door. Lisa appears at the top of the stairs and Steele tells her they have a sick friend. She directs them to a hospital farther up the road. When they ask where her parents are, Lisa says that she and her grandfather are the only ones there. The men hurry upstairs. Steele snaps his finger and waves Lomax’s cigar in the grandfather’s face, but he doesn't react. As a police car drives up outside, Lomax puts his gun to the old man’s head and tells Lisa to send the policemen away. Later, Lisa serves Steele and Lomax fried chicken. When Billy tells the two men to leave Lisa alone, Steele sends him upstairs to see if their crimes are being reported on the radio. Hearing a noise outside, Steele and Lomax spot a young man running away and chase after him, but he gets away. Upstairs in the bathroom, Lisa stares into the mirror, imagines blood on the glass and sees a black snake in the bathtub. She picks up a razor on the sink, turns on the hot water and tries to slit her wrist, but cannot bring herself to do it. Billy knocks on the bathroom door, and apologizes for Lomax and Steele. Lisa goes to her room and puts the razor in her bedside drawer. Steele and Lomax find a photograph of the grandfather when he was an army officer. When they taunt the old man, Billy gets angry and leaves. Looking more closely at Lisa, Lomax comments that she is a nice looking woman. That night, Lomax goes to Lisa’s room and finds her asleep. The room is filled with photos and toys from two generations earlier. Lomax unbuckles his pants and sprawls on top of Lisa. As he gropes her, Lisa reaches for the razor and kills him. Lomax's blood soaks the bed and splashes on Lisa's face. She goes to the bathroom to wipe the blood off her face, then drags Lomax’s body into the bathtub. Fetching her hand axe from downstairs, Lisa chops Lomax's body into pieces. The “thunk! thunk!” resounds through the house, but only her grandfather hears it. Afterward, Lisa puts the body parts into a trunk, mops the bathroom, and goes to bed. The next morning, Lisa gets Billy to haul the trunk up to the attic. Following him up, she notices blood leaking on the stairs. In the attic Billy sees the blood on his hands and opens the trunk. After his initial shock, he asks Lisa who did it. She says that Steele killed Lomax and said he would kill her if she told anyone. Lisa and Billy go for a walk in the woods, but she keeps the razor behind her back. Billy tells her he cannot go to the police because he is involved in a murder, and asks if she will help him take care of Steele. Lisa raises her hand, ready to strike, but when Billy sees the razor, he casually takes it, thinking she is giving it to him. He tells her to go back to the house and act as if nothing has happened. As Lisa fixes Steele a sandwich, he says she is a very pretty girl. Sensing his intentions, Lisa tells him she has to go tend her grandfather. Steele gets angry and pulls her toward the stairs. He assaults her in front of her grandfather, who is unable to do anything. Seeing an axe near the fireplace, Lisa grabs it and swings. Blood splatters on the television screen and all over her grandfather. Downstairs, she stirs red sauce in a pan on the stove. When Billy walks in and asks where Steele is, she says he went outside. Lisa goes upstairs and spoon-feeds the red sauce to her grandfather. When Billy comes upstairs and says he cannot find Steele, Lisa offers him a bowl of red soup. As Billy spoons the thick liquid into his mouth, he finds Steele's ring. Looking up, he sees blood dripping in the fireplace just moments before Steele's body drops head-first from inside the chimney. Billy hears a police car coming. As he runs out of the house, the police shoot him dead. Lisa sings softly to herself as she spoons more soup into her grandfather’s mouth.
