Auto mechanic Li Gang relied on a paint-mixing secret recipe passed down from his father and exquisite craftsmanship to help his cousin Li Qiang revive a failing auto repair shop, only to be repaid with ingratitude by Li Qiang—who swallowed a million-dollar dividend, slandered him for stealing technology, publicly humiliated him, and kicked him out penniless. When pushed to a corner, childhood friend Liu Fang offered all-out help. Li Gang held fast to his bottom line of integrity to start anew, gathered evidence to fight back, and ultimately brought Li Qiang to justice. He not only pioneered his own auto repair brand and reaped a fulfilling romance, but also used his perseverance to prove that a craftsman establishes himself by skill and goes far with integrity.
