A meteor hits a houseboat, turning its occupants into zombies feeding on alligators. As reptiles dwindle, they target townspeople. A scientist investigates disappearances caused by the undead houseboat dwellers.
A meteor strikes a houseboat in the swamps near a southern town populated by Yankees with fake accents. The people on the houseboat become zombies who feed on the alligators in the swamp. Once they run out of alligators, they start going for the citizens. A local scientist tries to figure out what's happening to people once they start disappearing.—Ed Sutton <esutton@mindspring.com>
