Ned Ravine is a police officer and lawyer who occasionally defends the delinquents he arrests. He crosses paths with seductive Lola Cain during an assignment and promptly begins an affair with her. Meanwhile, Ned's wife, Lana, is deep in an affair of her own. Lana and her lover are planning to murder Ned in an elaborate fashion so they can collect on his triple indemnity life insurance policy.
