A scuba diving instructor, her biochemist boyfriend, and her police chief ex-husband try to link a series of bizarre deaths to a mutant strain of piranha fish whose lair is a sunken freighter ship off a Caribbean island resort.
You've finally got a fix for "Hey you can beat this villain by just staying out of the water" and then they **barely ever use it**. Sure, it makes no sense that the piranha can fly, but seeing as they can, you may as well have used that ability to the max. But 99% of the victims are still water-bound. Whatever, it's a modicum of fun in that dated practical effects way.
_Final rating:★★ - Had some things that appeal to me, but a poor finished product._
