A mad stage hypnotist Dr. John Basso (Les Tremayne) reverts his beautiful assistant Doreena (Pat Delaney) into the physical form of a prehistoric sea monster she was in a past life. Using this power he attempts to find fame and fortune by predicting a series of murders and then using the monster to carry them out. Written by Jeremy Lunt durlinlunt@acadia.net

A color remake of "The She Creature", Les Tremayne is a mad hypnotist who regresses a girl back to a previous life, which, in her case, was a sea monster. The monster from this Larry Buchanan film was reused in his later movie, "It's Alive".
