A group of friends including Brady Turner, Claire and Duncan McKay go out on a boat trip on a lake in Southern California, but their joyful weekend turns into horror, when a giant killer crocodile searching for its stolen eggs, picks off anyone who gets in its way. Can they all escape in one piece or will they slowly and painfully fall to the mammoth reptile.

After a bank robbery, four criminals escape to Mexico, but a storm causes an accident which takes down the plane where several die in the crash. The criminals take it into their own hands to continue when one survivor is attacked and eaten by a crocodile. The criminals kill it, but from then on the mother Crocodile is on a killing spree with a goal to kill each survivor. But that is not the only worry, because they're trapped within it's world, and if it doesn't kill them, the criminals will.
