Cheng Jian (played by Zhang Shaohuai), a "love master" who specializes in resolving love disputes between men and women, never dreamed that one day he would be beaten up and stuffed into a seaside breakwater, and even face the dilemma of a public trial! A candid video of Cheng Jian and the mayor's wife (played by Chen Qiaoen) kissing passionately in a restaurant box is spreading like a virus on the Internet. This variety show host is about to be ruined. How can he use his eloquence to convince his "always fierce" agent girlfriend MiuMiu (played by Ke Jiayan) that he is innocent? All this chaos was caused by a top-secret commission from the city government. The mayor (played by Ma Zhixiang) asked Cheng Jian to pretend to be the mayor's wife who is a cheating wife, in order to quietly solve the wife's unknown "little secret" before the election. Now caught in an unexpected peach storm, how can Cheng Jian rely on his extraordinary observation to unravel the mystery and get out of the absurd political storm perfectly?
