Description：Xiaodong is a child who lives illegally. He has lived in the women's street with a shirtless guy since he was a child. He imitates normal children and "pretends to go back to school" every day. He and Shan Lao have been dependent on each other since he was a child, and Shan Lao treats him like his own son. Every day Xiaodong would go to Shan Lao's warehouse to "hunt for treasure" and then to his "secret base". On this day, Xiaodong arrived at the warehouse as usual, but unexpectedly met "Meat Ginseng" Xinxin and accidentally rescued her. At the same time, in order to avoid being hunted by the police, the gang leader Huo Shi Ge inserted the stolen diamonds into the cargo of the truck driver Pei Yi, because these diamonds Zihao and Pei Yi had a "destiny". A case of theft and kidnapping is intertwined with misunderstandings. Xiaodong gets the feeling of a complete "family". The fate of the four people walks together and ends up in the same place...
