A trio of hunters in the Louisiana bayous capture a monster called the Swamp Thing. They take it to New Orleans where (naturally) they display it in a strip joint. When the monster's favorite stripper gets into a fight with another stripper, he breaks loose and starts killing.

Based on the preachings of Reverend Estus W. Pirkle, this film warns what will happen to America if the citizens do not give up their depraved ways and turn to God and Jesus for salvation. Communist infiltrators, the "footmen," will pave the way for an all-out invasion by weakening our will through TV, dance, rock music, and alcohol. Once the invasion begins, the new Communist government will proceed to round up all Christians, and either execute them or force them to undergo re-education. Only by putting their faith in the Bible where it belongs, says Reverend Pirkle, can America resist the coming Red Menace.
