There are mysterious disappearances haunting a Florida swamp somewhere in the remote regions. There is something so sinister lurking under the surface, which locals believe is true.
In nearby Cape Canaveral, the atomic radiation has mutated giant human sized leeches that are snatching unsuspecting victims to their under water nest. These victims are kept captive in a flooded cave and are drained off gradually with blood by the intelligent slimy predators.
One of the earliest to disappear is Liz Walker (Yvette Vickers), a dissipated town woman who is involved in an affair. Panic sets in, game warden Steve Benton (Ken Clark) and his girlfriend Nan (Jan Shepard) enlist the help of her father Doc Grayson to help them find out the truth. They find the horrible lair of leeches, and the only solution to the nightmare is to blow it to pieces.
