In the near future, a mad scientist known as Henry Swanson creates the ultimate weapon in his eyes, a large 25-foot freshwater octopus, the first of its kind. The beast has a thirst for blood that cannot be quenched. When it escapes from its tank one lonely night under the watchful eye of the doctor, the town of Devil's Lake becomes threatened, and as people go missing, two local police officers do their best to find out where the missing have gone. When one such missing is found chewed up and torn apart, theories are spread all over the place, and it seems all fingers point to the strange man who lives in a mansion on top of the hill in town, that man being Henry Swanson. It is in the vein of all those great cheesy monster films of the late '50s and early '60s, but with the added vulgarity of a Troma picture. It may not be high class, but it sure is the lowest form of fun one could have.
