Mexican-born, New York-based filmmaker Alfonso Cuaron directed this Mexican box-office smash hit about a pair of randy upper-class buddies that sparked some controversy for it's frank depiction of drug use and sexual exploration. With their respective girlfriends away in Europe, Julio (Gael Garcia Bernal) and his upper-class friend Tenoch (Diego Luna) are looking forward to a summer full of drink, drugs, and cheap meaningless sex. During a wedding, they meet Luisa (Maribel Verdu) the 28 year old wife of Tenoch's scholarly cousin and try to convince her to go on a road trip to Heaven's Mouth, a made-up beach paradise the two claim is on the Oaxacan coast. To their surprise, Luisa; who is looking to escape her troubled life for a spell; agrees to go along. Two days into the trip, tension starts to build between the two friends: Luisa has had sex with each, and now both lads are not-so-quietly vying for her affection. Soon simmering jealousies boil over into savage arguments, threatening to completely destroy their friendship.
