This biopic about boxing legend Roberto Duran (Edgar Ramirez) follows his rise from a two-fisted street urchin in Panama to a gifted amateur known for Round 1 knockouts. Along the way he gains fame, riches and the love of Felicidad (Ana de Armas), but a chance meeting with boxing coach Ray Arcel (Robert De Niro) takes his fighting skills to a level where he can defeat American champion Sugar Ray Leonard (Usher Raymond). The lessons Arcel teaches his protégé about psychological cleverness in and out of the ring carries Duran through the darkest part of his career, when the notorious "No más" rematch against Leonard threatens to derail his entire legacy. Robert De Niro's adopted daughter Drena De Niro plays Ray Arcel's adopted daughter in this bilingual feature written and directed by Venezuelan director Jonathan Jakubowicz.
