In short, Piranha is Girls Gone Wild with killer fish that eats everyone. It’s a typical guy movie with lots of well-endowed girls swimming and dancing around on Spring Break. This B movie is somewhat a sequel to the movie of the same name, Piranha (1978) and Piranha II (1981). It also pays homage (or parody depending how you look at it) to the classic Jaws (1975).
The plot is simple. An earthquake releases ancient killer piranhas from an underground lake located under another lake and starts eating the spring break party goers. It’s very much like the movie 8 Legged Freaks, but with fish and scantily dressed girls to say the least.
