Mexican teenagers Julio (Bernal) and Tenoch (Luna) envision a guilt-free, sex-filled summer when their girlfriends go to Europe on vacation. At a wedding, they meet Luisa (Verdu), the wife of Tenoch's cousin, and begin a flirtation, telling her of their planned trip to a secluded (and non-existent) beach. When Luisa discovers her husband's infidelity, she decides to join the boys on their trip, and their adolescent sexual fantasies turn to emotional upheaval when she seduces them separately. Believe it or not, this is a comedy (and a funny one), with "American Pie" type jokes and shenanigans sprinkled throughout. But since this movie has a brain, and something of a soul, the consequences aren't always slapstick-funny. Spanish with subtitles.
