The wine taster Xu Zhi divorced because of her husband's derailment. The well-known TV personality Radar helped Xu Zhi's father and Xu Beiyang, a researcher at the Bird Research Institute, to punish his former son-in-law by mistake, but he fell in love with Xu Zhi. However, he was brutally encircled by Xu Beiyang, who became extra cautious about his daughter's marriage. Xu Beiyang's second daughter Xu Wei and her boyfriend Wang Chuang, who was regarded as frivolous and immature by her father, secretly obtained a marriage certificate and made a fake pregnancy. Xu Beiyang was furious and personally supervised the two people to make people. The French niece promised to return to China to find a boyfriend. She first found an old man who was one year older than Xu Beiyang, and then talked about marriage with Luo Shixiong, a second-generation rich man. Pressing the gourd and the scoop, Xu Beiyang, who had lost his wife for many years and was not good at handling housework, was miserable. The daughter was the little lover of her father in his previous life. The daughter's marriage made Xu Beiyang "jealous" and heartbroken without a trace. For the lifelong happiness of his daughters, Xu Beiyang decided to strictly control the selection of son-in-law and come up with various tricky ways to test the three sons-in-law. Radar couldn't bear the burden, so he formed a son-in-law alliance with Wang Chuang and Luo Shixiong to fight against his father-in-law! After a game, Xu Beiyang finally understood and accepted the three sons-in-law, and the father-in-law and son-in-law reconciled.
