Los Monstruos del Terror

Aliens from a dying world inhabit the bodies of dead Earth scientists. Led by Dr. Warnoff (Michael Rennie), they bring back to life humanity's most feared monsters: a vampire, a werewolf, a mummy and the creature made by Dr. Frankenstein. But the goal of cloning their creations into a world-conquering army hits a snag as the aliens start feeling the human emotions of their host bodies, and the love-struck werewolf, Daninsky (Paul Naschy), becomes a one-monster army against the other horrors.
