Li Meng is an ordinary person who lives at the bottom of the society, but his appearance is very similar to Tang Yao, a real estate tycoon. After being sick and hospitalized, Li Meng was discovered by Tang Yao's secretary Lin Pei. Seeing that he looked the same as Tang Yao, he had an idea to ask Li Meng to be Tang Yao's substitute to host the company. Because Li Meng was framed by someone before, he innocently lost hundreds of thousands of dollars while playing billiards in the billiard hall. Later, the owner of the billiard hall hired migrant worker Da Li Xiaoli to find Li Meng to collect debts. Yes, but because he was deeply in debt crisis, he had to compromise, and finally agreed to be Tang Yao's stand-in. After that, Li Meng became a wealthy man in the company, but because he had been living at the bottom of the society, Li Meng didn't understand many things and made a lot of jokes. A series of training, Lin Peiming with a very vicious style, called Li Meng, in the training process, life was like death. But what makes Li Meng even more uncomfortable is that he has to deal with the threat of Tang Yao's wife, Qin Yuyan, and the company's second boss, Wen Pengfei. After that, Li Meng used Tang Yao's identity to do many good deeds, but at this time, Kiss Pengfei was also weaving a big net for Li Meng, waiting for Li Meng to step into the abyss step by step
