A wealthy lord dies and is entombed with a valuable deposit of jewels. Seven keys are required to unlock the tomb and get hold of the treasure. A mad doctor uses an iron maiden to systematically eliminate the heirs to the fortune.

What do women want? Don Juan is aging. He's arrived secretly in Seville after a 20 year absence. His wife Dolores, whom he hasn't lived with in five years, still loves him. He refuses to see her; he fears the life of a husband. She has bought his debts and will remand him to jail for two years if he won't come to her. Meanwhile, an impostor is climbing the balconies of Seville claiming to be Don Juan.
