El Santo, the masked Mexican wrestler, is called in to investigate a series of kidnappings. He then discovers that the mysterious Doctor Caroll (Claudio Brook) is using the victims as part of his experiments to develop an army of monsters. Naturally, EL Santo is able to overcome them all–by wrestling! (In Spanish language).
