Chen Jianguo, a mechanic in a fishing village, is publicly accused of harassing a woman by his ex-wife. He immediately produces a money transfer receipt proving that she had been sending money to her former lover, and decisively divorces her. He saves Ye Qinghe, a young woman working at a coastal radio station who conceals her true appearance. He protects her reputation and teaches her to read and write. The two become engaged and register their marriage. His ex-wife, having foolishly trusted a gambler, is tricked into going to the city to work off her debt. Chen Jianguo and Ye Qinghe help her escape by calling the police. With the villains brought to justice, Chen learns to read and write, starts supplying goods, and the family is finally reunited.
