When Paco and Trini come back to Madrid, he is willing to continue his twin relationship, but Luisa - who knows of Trini's existence - is wildly jealous of her rival. Things become more complicated for Paco by Luisa's shady business dealings with Minuta and Gordo, members of a gang of swindlers to whom she owes money. They have threatened her life, and Paco, attempting to aid his lover, suggests that he get the money by swindling Trini of her savings. Luisa would prefer that they simply kill Trini, but proposes that Paco should marry Trini, then steal her savings and run away with Luisa. Paco uneasily agrees.
