When wealthy businessman Qin Zhengshan is hospitalized with a serious illness, surveillance footage captures his younger brother, Qin Zhengming, and nephew, Qin Hao, plotting to pull out his oxygen tube and seize his estate. To strike back at these ungrateful wolves, he spends tens of millions hiring Cheng Ye, a brash supporting actor, to impersonate his biological son and return to the Qin family to fight for control. Cheng Ye refuses to play by the rules of the wealthy elite, repeatedly humiliating the villains and gradually taking control of the group's real power. At a wedding banquet, a secret buried for twenty-six years unexpectedly comes to light. A paternity test confirms that the supposedly fake young master he hired is actually Qin Zhengshan's biological son, who was lost to him long ago. In the end, Cheng Ye protects his birth father and brings Qin Zhengming's entire family to justice.
