The life of a man who preys on unsuspecting women for a living is changed when he finds an accomplice in the woman who loves and controls him.

Set in 1940s northern Mexico, this film re-tells the story of "The Lonely Hearts Killers", a famous couple of murderers who made victims of lonely and wealthy widows in the USA. Coral (Orozco) is a rotund and passionate nurse who knows handsome gigolo Nicolas Estrella (Gimenez Cacho) and falls for him immediately. Nicolas rejects her because she's not rich, but Coral is determined to get him at any cost. She abandons her children and follows the man in spite of his lifestyle. Together they scheme to swindle and murder women who look for love and companions writing letters to a sentimental courier.—Maximiliano Maza <[email protected]>
