The Devil is a Woman

Antonio Galvan (Cesar Romero), a young military officer, meets a mysterious and alluring woman named Concha Perez (Dietrich) and soon falls under her seductive spell. Antonio excitedly confesses his love for Concha to his friend Don Pasqual (Lionel Atwill), an older and higher-ranking officer. Pasqual is horrified when he learns of Antonio's infatuation; years ago, he met Concha, and it was the start of a long and disastrous relationship in which the cold-hearted woman would repeatedly lure him into her romantic web, drain him of his wealth, and then leave him for wealthier prospects elsewhere. While he has learned the hard way, Pasqual has never been able to cure himself of his addiction to Concha's charms, and when he encounters Concha with Antonio at a boisterous street festival, Pasqual is overcome with jealousy and challenges Antonio to a duel for Concha's affections.
