James Lake (Raymond St. Jacques) is an escaped black convict imprisoned for a murder he didn't commit. Leslie Whitlock (Kevin McCarthy) offers James money to kill his wife, Ellen (Dana Wynter). He declines and tries to look up his old flame Lily (Barbara McNair), but discovers his own brother is now married to the sultry nightclub singer. James returns to Leslie, and the trio travel towards a mountain retreat. James and Ellen escape and try to find the murderer who had framed James years before.

Officer Jim Wade is a loose cannon on the force with a reputation for roughing up suspects, informants, witnesses, and just about everybody else who rubs him the wrong way. When women start being killed by a mysterious serial murderer called The Slasher, Wade vows to put a stop to the killing spree, regardless of whether through legal means or not.
