A madman drags one beautiful woman after another into his dark labyrinth of horror beneath the murky canals of Venice. The girls are then embalmed by the skull-masked monster who places the corpses on display as captive zombies in an underwater tomb. Andreas, a reporter, is investigating the disappearances. Unable to convince the police that the missing girls are victims of a maniac, he probes deeper into the cases. Donning scuba gear, the killer stalks his prey, once again sending an innocent girl to her death in his subterranean lair. A nubile young woman accidentally discovers the grisly secret of the Embalmer, sealing her fate and perhaps that of Andreas as well!
