On the night of their fifth wedding anniversary, Su Yan mistakes her husband Jiang Nian's old lottery ticket from the previous draw for a winning ticket worth 80 million. Determined to keep the entire prize for herself, she insists on divorcing him and turns to her first love, Cheng Hao, who appears to have a successful career. She even mortgages their property to invest in his company. Little does she know that Cheng Hao is already drowning in debt and has teamed up with his girlfriend, Tang Lin, to deceive her out of her money. Eventually, Cheng Hao's fraudulent overseas order scheme is exposed, leaving his company on the brink of bankruptcy. Meanwhile, Jiang Nian, who actually won the 80 million, has quietly acquired a controlling stake in the company and finds happiness with Yan Li, a colleague who has always been there to support him.
