The old chairman of the Lin family, a modern wealthy family, suddenly fell seriously ill, and his two illegitimate sons Lin Xiuyuan (trainee lawyer) and Shen Yanqing (underground boxer) were recalled to the family at the same time to compete for inheritance rights. From the first tit-for-tat meeting, the two launched a series of battles of wits and courage: Lin Xiuyuan used legal means to lay out the plan, while Shen Yanqing used force and anti-reconnaissance capabilities to fight back, competing for the core projects of the family business, winning over the support of the elders, and revealing each other's secrets. In the process, the two people have emotional entanglements due to their feelings for the heroine (or their mutual appreciation), and finally achieve self-growth and emotional belonging while resolving the family crisis.
