Twenty years ago, Tyson Long became the Boxing King by defeating Green, whose revenge led to Tyson's father's death. Forced to vow never to fight again, Tyson restrained his strength and hid as a janitor. Now, his daughter Chloe leads their gym and insists on entering the reopened Boxing King Championship, defying Tyson's pleas and even cutting ties with him. Learning of this, Green sends Panther to force Chloe to forfeit by humiliating the gym with a death-waiver fight. When Panther uses dirty tricks to endanger Chloe, Tyson finally intervenes, using his restrained skill to protect her and face his past.
