As victim of horrific nuclear experiments a common house-cat mutates into a flesh-eating monster whilst maintaining its benign exterior form. It escapes into the wild - Fort Lauderdale, Florida during Spring Break. Having killed multiple people along the way it is discovered and adopted by flighty young airhead Suzanne (Shattuck) who is headed for a yacht excursion with her friends.
The yacht is owned by lecherous opportunist and Wall Street crook Walter Graham (Cord). His thug associates - drunken imbecile Albert (Gulager) and crude misanthrope Mike (Kennedy) are with him. As the authorities close in Graham elects to alter the course of the boat away from the coast and toward the Cayman Islands where he has stashed his ill-begotten assets. The college kids go along as crew.
While the kitty-cat gets into mischief a distracted Walter puts the moves on each of the younger women on board. The cat very efficiently sabotages the boat and preys on its passengers infecting them with his bites while eating them.
This howler of a low-budget direct-to-video turkey has some of the worst acting performances in history. By the final third of the film it becomes a highlight of appalling reaction shots and forced line delivery. Before that the audience is witness to the rampage of an obvious hand-puppet portraying the title monster.
The ponderous editing and other post-production miscues are enough in and of themselves to thoroughly embarrass some pretty gifted and respected actors in the cast (Kennedy, Cord, Gulager and Carey). Likely they also served to thoroughly embarrass some not so gifted or respected actors in the cast (Hudson, Estes and Shattuck).
