The movie stars Judd Nelson as a wealthy but unstable hermit who is convinced he will soon become insane much as his father did; his father actually did go insane and murdered Nelson's character's mother. He hires a private investigator (played by Vincent Spano) to look into his wife's possible motives for helping drive him insane. The wife, played by Jennifer O'Dell, is a sort of trophy wife; Nelson's character is certain that she is out to both drive him insane and rob him of his fortune.
