Rachel is a divorced single mother whose bad day gets even worse. She's running late to drop her son off at school when she honks her horn impatiently at a fellow driver during rush-hour traffic. After an exchange of words, she soon realizes that the mysterious man is following her and her young son in his truck. A case of road rage quickly escalates, at horrifyingly psychotic proportions, into full-blown terror as Rachel discovers the psychopath's sinister plan for revenge. He is single-mindedly determined to teach her a deadly lesson.

Kale has a life most teenagers would envy. He spends his days endlessly playing video games, surfing the net, eating junk food and watching cable. He has complete free reign of the house, and a beautiful young hottie named Ashley has just moved in next door. There’s only one problem—he’s not allowed to leave the house. Kale’s under court-ordered house arrest for three months, and if he takes one step beyond a 100-foot perimeter of the house, his next confinement will be in a real prison.
