An underwater seismic shift unleashes a furious breed of previously-extinct fish, which feed on the oblivious revellers on an isolated lake during Spring break.

The film is about 20% fish and 80% bikinis, breasts and the development of 3D shots. Not as rubbish as you may have been led to believe, but still, it does seem like a pointless experiment. It bares very little resemblance to the 1978 Joe Dante film of the same name.
