Xie Feng, a construction worker, is cheated out of six months' wages by a crooked foreman, Zhao Dahe, who pays him with the deed to a dilapidated house at No. 18, Lizhuang. Six months later, Lizhuang is designated for demolition, and the worthless deed turns into 40 million in compensation. But on the very day he receives the demolition notice, his wife, Qian Qiaoyun, has already been manipulated by Gao Liang, a fake rich second-generation heir. She brings her parents to the civil affairs bureau to force Xie Feng into a divorce. Heartbroken, Xie Feng signs an agreement to leave the marriage with nothing and keep their debts separate. After the divorce, he discovers numerous suspicious details about Gao Liang and clashes with him while picking up his son, Xiaobao, from kindergarten. Qian Qiaoyun takes custody of their son, declaring that only someone who can afford a house deserves to raise a child. In secret, Xie Feng uses the demolition compensation to buy back the old house and plan for his son's future.
