Piranha 3D

Every year the population of sleepy Lake Victoria explodes from 5,000 to 50,000 for Spring Break, a riot of sun and drunken fun. But this year, there's something more to worry about than hangovers and complaints from local old times; a new type of terror is about to be cut loose on Lake Victoria. After a sudden underwater tremor sets free scores of prehistoric man-eating fish, an unlikely group of strangers must band together to stop themselves from becoming fish food for the area's new razor-toothed residents.
