Lin Jun, an entrepreneur and company president, sees his marriage to his wife, Yu He, fall apart. His greedy mother-in-law, Yu Qingqiu, wants to remarry a much younger man, Li Dong, and pressures her daughter to hand over the 30% stake in Lin Jun's company that he gave her. But Li Dong is actually a romance-investment scammer, secretly backed by Zhu Dongyuan of Dongyuan Group, who is plotting to seize the company. Lin Jun carefully sets his plans in motion, turns the enemy's informants against them, and uses various factions to keep one another in check. Gradually, he exposes the conspiracies of Li Dong, Yu Qingqiu, Zhu Dongyuan, and the others, ultimately sending the greedy schemers to prison. Having protected his business, he joins hands with a kind-hearted medical trainee to begin a new life.
