I travel back to the 1990s and become a gambling addict who has lost the entire family fortune and even stolen his daughter's medicine money. With creditors blocking the door, I have three days to repay 500 yuan, or they will take my wife and daughter away. Everyone expects me to gamble again, but I am determined to turn my life around using the overlooked soapberry tree in the courtyard. From shampoo selling for 50 cents a jar to a 1,500-yuan soap order, my wife and daughter finally begin to trust me again. But just as Tao's Soap enters the county market, a customer suffers chemical burns from a poisonous bar of soap. Even more shocking, the poisoned soap bears a secret identification number known only to me and my benefactor. Who is determined to make sure I never get back on my feet?
