Former Sanda champion Lin Ting is forced to join forces with the mysterious boxing champion Chen Han who has returned from overseas in order to save his family martial arts gym. Above the arena, they are the pinnacle of force that makes capital tremble; below the arena, they are enemies with very different ideas and tit-for-tat confrontations. When traditional martial arts encountered the encirclement and suppression of modern fighting, and when pure passion became pawns in the game of capital, they decided to break the rules and create an era of their own with their fists. This is an evenly matched confrontation, and it is also a top-notch love that is bred in sweat, blood, and fighting side by side.
