A close circle of friends and relatives become involved in a complicated game of musical beds in a spicy satirical comedy for adults. Angel (Sergi Lopez) is married to Ana (Aitana Sanchez-Gijon), but while he stays with her for the sake of their four children, he hasn't been very happy in their relationship for some time, and is often unfaithful to his wife. Angel's brother, Hermano (Pepon Nieto), has just the opposite problem; his wife seems to have lost interest in him, and he discovers she's been having an affair with his boss. As Hermano tries to hold on to what's left of his pride, Ana becomes convinced Angel has been unfaithful to her, and in order to test her husband, she convinces her friend Amiga (Maria Esteve) to try and seduce Angel. The plan works a bit too well, and Amiga ends up sleeping with Angel. Ana tries to convince herself that this shouldn't affect her friendship with Amiga, but to spite her husband, she begins having an affair with Hermano -- something she keeps a secret from her husband until she finds him in flagrante delicto with his secretary. ~ Mark Deming, Rovi
