Piranha Women is a good little short horror film from "Full Moon Pictures" by Fred Open Ray.
An island doctor is using piranha DNA to cure sick women. When Richard's girlfriend goes to the doctor, asks him to stay out all night, then leaves while he's at work the next day he decides to investigate what's going on.
The previous evening, Richard and his buddy/coworker, Jeffrey go to a small local bar. Jeffrey leaves with a woman from the bar, and ends up dead. This leaves Richard as the main suspect. He returns to the bar to try to figure out what happened and clear his name.
He learns about the piranha DNA and sets out to rescue his girlfriend.
The idea of "Piranha Women" is pretty cool. The effects aren't bad for this type of movie. Worth checking out 7/10.
