While investigating the mysterious death of a diver, scuba instructor Anne Kimbrough (Tricia O’Neil, Are You In The House Alone?) makes a horrific discovery: mutated piranhas, with wings that enable them to fly, are responsible for the death. As the body count rises, Anne desperately tries to convince the manager of the resort to call off the annual fish fry on the beach, but he’s determined to give his guests the ultimate feeding frenzy. 

Roger Corman sold off the rights to the sequel (deciding to instead focus his energy on Humanoids from the Deep) to Ovidio G. Assonitis (Beyond the Door), who eventually hired a young aquatically-obsessed special effects up and comer, James Cameron, to take the helm! Though not well received upon release, this scrumptiously gory, sleazy, and admittedly ridiculous affair led by a way-too-strong performance from Lance Henriksen, has rightfully become a beloved cult classic ready to remind viewers that even if you're not in the water, you're still not safe!
