Fan Jianqiang (Xu Zheng) is a national second-level consultant who runs an ordinary psychological clinic and earns a monthly salary of 4,000 yuan. He has no house or car, but has a sexy and beautiful flight attendant girlfriend, Su Qian (Lin Peng). Mid-Autumn Festival is the day he and his girlfriend agreed to meet his father-in-law and mother-in-law. After urgently ending the psychological treatment of the patient Diaokengnan (Ren Long), he and his girlfriend drove from Shanghai to the home of Su Qian's parents in Hangzhou in a car borrowed from his best friend Wu Fendan (Guo Mingxiang). As soon as he arrived at Su Qian's house, Fan Jianqiang was shocked by the scale of the villa in front of him, and what surprised him even more was that Su Qian's father turned out to be his patient, the windbreaker uncle Su Bohu (Xu Shaoxiong). Su Bohu is a very prestigious professor of economics. He attaches great importance to his reputation and does not believe in Fan Jianqiang's professional ethics. He is worried that his unknown secrets will be leaked by Fan Jianqiang, which will ruin his reputation, so he wants to drive Fan Jianqiang away. The questions Fan Jianqiang prepared in advance to answer his father-in-law and mother-in-law could not fool Su Bohu, who had previously given him advice, so he had to be honest. The two who knew each other well had constant conflicts and a lot of jokes as soon as they met. Can the poor Fan Jianqiang gain the recognition of his father-in-law and finally deal with his father-in-law?
