The nightmare begins when Captain Lansen (Eric Porter) attempts to transport illegal explosives and a motley group of passengers on a rusty tramp steamer that becomes stranded in the vast floating swamp of the mysterious Sargasso Sea. Under cover of night, the terrified travelers encounter unspeakable monsters, man-eating seaweed, vicious mutant pirates, and stupendously endowed women. (official distributor synopsis)
