Deep in the Florida Everglades, something is alive that should have died eons ago. Something is feeding when it should be full. Something is moving, in ways that seem all but impossible to pursuers. Its moving in the dark... under the surface of the waters... with an appetite that makes no distinction between man or beast. Now its up to an unlikely band of locals, an animal control officer, a small town sheriff and a scientist’s team of college youth to stop the threat... before its too late.
