Injected with a serum containing the genetic traits of a cat, Tom is restored to health and transformed into a sinewy hunk with superhuman agility and a decidedly feline demeanor -- complete with a savage, murderous sex drive. Though this added trait makes him doubly attractive to his doctor, it also compels him to destroy every woman with whom he mates. Though the majority of the film's tension is of the sexual kind (and quite steamy at that), the more horrific plot elements are well-driven by Grieco's manic intensity -- until the disappointing climax, which shows the earmarks of a writer in over his head.
