1999, Rome. Giorgio, a young promise of boxing, lives with his mother in the run-down outskirts of the city. The father, murdered years earlier, bequeathed to his son a debt to the underworld that does not allow him to be a free man. With the help of Massimo, who has a background in boxing and sees in the boy the great champion that he did not manage to become, Giorgio finally has the opportunity to redeem himself, entering the world of professional boxing. But the suburban underworld never leaves a chance to those who don't bow to his rules.
