Will Ferrell stars in this parody of a 1970s Mexican telenovela B-movie, complete with intentional continuity errors, bad acting and dodgy edits. Black sheep of the family Armando Alvarez (Ferrell) welcomes the return to the family ranch of his prodigal younger brother Raul (Diego Luna), but is jealous of Raul's beautiful fianc�e Sonia (Genesis Rodriquez). As he struggles to come to terms with his own feelings for Sonia, he must face a more pressing threat in the form of Mexico's most feared drug lord, Onza (Gael Garcia Bernal), who has set his sights on the ranch.
