Rejected by his own parents for the uncontrollable power in his fists, a gifted young boxer finds a new home at Sister Qing's humble boxing gym. Once just a sparring partner, he risks everything to protect the woman who saved him and the gym that became his family.
But when his beloved master is murdered, his world falls apart. With no clues and no justice, he sets up an open challenge ring, forcing every powerful fighter to face him—until the killer finally steps into the ring.
One fight. One truth. One final revenge.
