Retired veteran teacher Zhao Deming gave everything for his biological children throughout his life, selling the old house to buy a house for his son Zhao Qiang and subsidizing his retirement pension month after month, only to be driven out of the house by his son and daughter-in-law when his in-laws visited, even having his house keys taken away. Just as he was down and out and helpless, his five impoverished students whom he had supported to study back then have now returned as top tycoons in various industries, wanting to repay his teaching grace. Zhao Qiang initially looked down on his father's old students, bent on currying favor with the chairman of Dingsheng Group to forge his future, and publicly forced his father at the hotel to confess to falsely claiming to be the big shot's benefactor teacher, until the five tycoons appeared, only to realize that the biological father he treated so poorly was precisely the one respected by the big figures.
