Qin Zhenhai, a powerful underworld figure who retired many years ago, quietly raises his daughter, Qin Zhiwei, while living inconspicuously as an ordinary ride-hailing driver. At his daughter's engagement banquet, the snobbish Gao father and son repeatedly make things difficult for them because they look down on Qin Zhenhai's lowly status. Qian Li steals his parking spot and slaps him. The Gao family forces Qin Zhiwei to sign a prenuptial agreement that would leave her with nothing, forges a pregnancy test report to slander her virtue, and even demands that Qin Zhenhai kneel and serve tea. The spoiled heiress Su Ruoxi also arrives to join in the humiliation. Qin Zhenhai secretly contacts his former subordinates and three sworn brothers who once risked their lives for one another. Zhao Zhenguo, chairman of the Xingbang Consortium; Han Lie, a cross-border logistics magnate; and Long Tianbao, an underground kingpin, arrive one after another bearing extraordinarily valuable engagement gifts.
