Lawyer Rick Magruder has a one-night-stand affair with caterer Mallory Doss. He becomes hooked on her, and when he learns her nut-case father Dixon is threatening her, he puts the weight of his law firm behind Mallory, has Dixon arrested and subpoenas her ex-husband Pete to testify against Dixon in court. Dixon is sent to an asylum, but escapes from there and the lives of many people are in danger.
