Mentally disturbed woman always ends up killing her lovers.

The beautiful Isabel is fascinated by the life of the notorious homicidal conqueror Landru. Devoting herself to reconstructing her idol's crimes, she sexually lures several men and murders them. In carrying out her crimes, she enlists the help of Tula, her hunchbacked maid, who is eager to take sexual advantage of the men her mistress brings along. Meanwhile, Isabel's brother, Tristan, plans to sell the house where she lives by leading her into a forced engagement.—Bernardo74
