Two brothers embark on a life-changing course when Sebastián (Aarón Díaz) persuades his older brother -- who quit bike racing after an accident -- to join him in his quest to become a professional racer. The siblings soon set off for Sin City for a motocross event, where they push themselves to the limit. Irán Castillo, Plutarco Haza and Ximena Sariáana also star in director Chava Cartas' adrenaline-fueled action adventure.
