A psychotic man opens fire in a diner, murdering numerous people before killing himself. The survivors struggle in different ways following this horrendous event: a doctor doubts his own instincts and elects to use an experimental medical procedure on his wife, while a gambler believes he's on a lucky streak. A waitress begins engaging in promiscuous sex, and a young girl whose father is among the dead gains unexpected fame.

A pathetic police chief, humiliated by everyone around him, suddenly wants a clean slate in life, and resorts to drastic means to achieve it.

A trucker encounters a dead body on the road home. He reports the incident to the police, who suspect that Jean was responsible for the death, and his new truck is impounded. To make matters worse, the man's widow accuses him of having robbed her husband, and a gang of sinister crooks are also harassing him.
