In his first film El Santo was still referred to as ‘El Enmascarado’. Rendered compliant by a scientist and his gangsters via a serum and mysterious rays, he is forced for the opening act to be a henchman for the evil forces who want to take over the world. The film has great historic value, due also to its impressive exterior shots of pre-revolutionary Cuba 1959.
