Xu Lang (Xu Zheng), a successful businessman, spent five years inventing a magical product called "Oil Tyrant" - every time the car is refueled, only two-thirds of the gas is needed, and then two drops of "Oil Tyrant" are added, and the gasoline in the tank will become a full tank. Xu Lang's classmate and business competitor Gao Bo (Huang Bo) wants to sell this invention to the French at one time. But Xu Lang firmly disagrees. He hopes to conduct in-depth research and development to promote "Oil Tyrant" and get more benefits. The two people expressed their opinions and argued endlessly, but to no avail. Since the two have the same shares, they can only achieve their respective goals by obtaining a letter of authorization from Zhou Yang, the company's largest shareholder. When Xu Lang learned that Zhou Yang was in Thailand, he immediately set out to find him. After Gao Bo learned about it, he put a tracker on Xu Lang and went to Thailand together. On the plane, Xu Lang meets Wang Bao (played by Wang Baoqiang), who wants to use him to get rid of his rival Gao Bo. However, he not only fails to get rid of Wang Bao, but also becomes his "personal nanny"... Who will get Zhou Yang's authorization letter in the end? And what kind of hilarious and magical journey will these three people with different purposes bring to Thailand?
