After having a nervous breakdown, former ballerina Elsa Spann gives up her career to live in a trailer park with her husband Carl. One evening, he returns home and finds everything in disarray. Elsa tells him she was attacked by a man who almost killed her. Instead of going to the police, a vengeful Carl decides to get his own justice. He takes Elsa for a drive. On the way, she points to a man whom she says attacked her. Carl follows the man and kills him. As the couple head home, however, Elsa points to another man whom she says was her attacker. As police pull up behind them, Carl realizes his wife has gone crazy and that he has just killed an innocent man.
