La petición (1976)

A wealthy heiress is sucked into a forbidden affair with one of her servants’ sons in the smoldering Italian-Spanish romantic thriller La Petición (1976). Ana Belén stars as Teresa, a glitzy aristocrat who can’t be bothered to give the livery the time of day. The one exception, however, is the handsome son of one of her servants, with whom Teresa becomes infatuated. After luring him into her chambers for a frenzied boffing, Teresa flies off the handle and brains the poor schlub. The remainder of Pilar Miro’s film chronicles how the vixen covers up her dastardly crime. Belén’s clearly bad news, but it’s easy to see how her charms might prove irresistible––she’s got a rack that’s truly in a class by itself.
