Sun Sheng was originally a proud son of heaven, with a prominent family and a smooth life. But due to an accident, the tall building collapsed overnight. In order to protect the family, his father concealed the truth and deliberately created a suicide scene to lie dormant. His mother was unjustly sentenced to twenty years, and the family was saddled with a huge debt of five million out of thin air.
In the past, all his relatives and friends avoided him, but Tian Peng, a low-level gangster, never left him. In order to repay the debt, reverse the case, and survive, Sun Sheng put aside all dignity and stepped into the lowest level of the gray world. Starting from the first debt collection job, he suffered humiliation and struggles, but he always managed to survive in desperate situations. There seemed to be an invisible hand paving the way for him.
