Professional billiards player Jiang Jianhao lost his right hand because he refused to match-fix, and fell from the top to the abyss. In his darkest moment, "left-handed genius" Shen Yanqing "picked" him up and took him home, forcing him to start over again in the cruelest way. From rival to master and apprentice, from partner to each other's only existence - when the right hand loses its glory, the left hand will rewrite the legend. This is not one person's counterattack, but two people's redemption.
