Known as Samson vs. the Vampire Women in the U.S., this is one of four Santo films that were dubbed into English and released north of the border. Blame K. Gordon Murray, a distributor of Mexican films whose movies mainly played children-friendly weekend matinees or late night TV thanks to American-International TV.
A coven of vampire women awaken in their crypt after two centuries of sleep. Their leader, Queen Zorina, just wants to go back to Hell with her husband Lucifer — man, I love this movie — and to get here there, Tundra makes a vow to take the granddaughter of a woman who escaped her evil grip.
The only person that can save her is Santo, as his grandfather once saved the day all those years before. To get there, he’s going to have to fight a werewolf and then all of the vampire women, who decide they need to see Santo’s face, but the fun comes up and they all explode into flames. The silver masked man jumps in his convertible and drives away, satisfied with killing monsters for today.
