An unnamed serial killer is eager to kill again following his release from prison, driven by a desire to see the fear in the eyes of his victims. He stops by a diner, where he is tempted to attack two girls sitting at the counter but is unable to act on this inclination in public. In a taxi afterwards, he prepares to kill the female driver but is forced to flee when the driver becomes suspicious and stops the car. The killer comes across an empty house during his escape and breaks in. Inside, he finds an intellectually disabled man who uses a wheelchair. He mistakes the killer for his own father. Soon, the man's mother and sister arrive at the house, and the killer hides before eventually attacking them, taping the daughter to a doorknob and strangling the mother. He ties up the mother before dragging the son to the upstairs bathroom and drowning him in the bathtub.
