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 timers; A new type of terror is about to be cut loose on Lake Victoria.
After a sudden underwater tremor sets free scores of the 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.
