Car mechanic Zhao Chengan hands over all his salary year after year to help his in-laws and support his brother-in-law. When his wife, Zheng Li, refuses and humiliates him for buying a pair of 58-yuan work shoes, he has to rely on a friend to borrow money to get out of trouble. After seeing through the coldness of their eight-year marriage, he resolutely asks for a divorce. He is then framed by his former boss, Jiang Guoliang, and forced to bear a 68,000-yuan loss for a brake accident. After being fired, he is also smeared in the industry. Zhao Chengan sets up his own auto repair shop on his own, gathers evidence to prove his innocence through labor mediation, ultimately refuses his ex-wife's attempt to reconcile, and establishes a firm foothold with honesty and craftsmanship.
