In a movie, a father spared no expense to find his son, and someone pretended to be his son for money.

Li (Yu Entai) and four unreliable college girlfriends set up a company called "Looking for People under the Lamp", but the performance was bleak. He borrowed the Mercedes-Benz of the landlord Liu Panda (Gao Yalin) to pick up the flight attendant's girlfriend Qing Qing (Wang Lanfei), but was dumped because he didn't buy the limited brand-name bags and fiber planting that his girlfriend wanted. Finally, when I switched back to running, I rear-ended the police car of policewoman Kang Hong (Tan Zhuo), which caused a misunderstanding.

When Li learned from the newspaper that Mr. Wangzhuang Yigui (Lin Dongfu), a billionaire, former national army major and now a Thai chicken, was going to spend a lot of money to find his long-lost grandson, Li led the company's employees to join the army of "finding relatives". After hardships and full of jokes, when he finally thought he was close to his goal, he found himself caught in a huge scam. He was forced to continue cheating. Although the scam was successful, the desire for money made him blind, and the desire for money made Qingqing fall into the arms of a "fake grandson".

The scam was finally exposed, and Kang Hong, a policewoman who had been staring at him, personally participated in the case investigation. In the pursuit of The Scholars, the contradiction between him and Kang Hong turned into complaining to the judge.
