When Qin (Fan Wei), an ex-convict in his 50s, receives 1.5 million yuan in demolition compensation from his late parents’ home, he dreams of starting over by settling down and having children. However, after getting scammed by a marriage agency, he decides to take matters into his own hands and posts a matchmaking notice outside a women’s prison. There, he meets Chang Juan (Zhou Dong Yu), a recently released 24-year-old, and the two begin to spend time together. While initially hesitant due to their large age gap, Qin accepts Chang Juan's proposal of marriage, providing a dowry of 184,400 yuan deposited directly into her account at her request. But after a heated argument over having a child leaves her hospitalized, Chang Juan suddenly disappears – along with the money. Can Qin find Chang Juan and resolve their differences, or is this just the beginning of something even more serious? This movie was adapted from the novel "The Murderous Girl in a Wedding Dress" by Xia Long.
