The fifth-tier town Xiangcheng is preparing to transform and host an international event: a 10,000-person marathon. As soon as the news came out, people from all walks of life appeared around this event. Zhang Kuang, a local youth, wanted to become bigger and stronger. He planned to win the right to host the marathon and rise from then on, but he was unexpectedly involved in counterfeit money transactions, and the elephant borrowed from the circus disappeared. In order to continue his glory, Zhang Kuang had to borrow money. Unexpectedly, the creditor was the local gangster Gou Ge who was declining. He had been eyeing the circus land for a long time and wanted to outsmart it, but he was not smart enough and lifted a stone to hit himself. At the same time, Uncle Zhi and Sister Hei, who started out as counterfeit money in their early years, also had their own troubles. With the rise of electronic currency, counterfeit money has become a sunset industry. They want to use this marathon to clean up the last penny of stolen money. Zhang Kuang, who was kept in the dark, became a scapegoat. And Zhang Kuang's only goal is to successfully finish this marathon!
