Boxer Esteban Osuna, nicknamed The Machine, suffers a defeat in a high-profile bout. He is almost forty; he struggles with alcoholism, and he experiences hallucinations and memory lapses. His manager and childhood friend Andy arranges a world-title rematch for The Machine. For Esteban, this is the perfect opportunity to perform with dignity and leave the sport gracefully. But earlier, Andy had made a deal with a mafia organization, and now Esteban must deliberately lose the fight, or else they both will face deadly consequences.
