Summary:
The passengers of an old freighter en route to South America find that their voyage is truly damned! The nightmare begins when Captain Lansen (Eric Porter) attempts to transport illegal explosives, and their rusty tramp steamer becomes stranded in the vast floating swamp of the mysterious Sargasso Sea. Under the cover of night, the terrified travelers encounter unspeakable monsters, man-eating seaweed, vicious mutant pirates and stupendously endowed women.
