2005, Songjiang, Northeast China. Zhou Yuan, a cooperating police officer who is about to turn 22, follows his master, Lao Ma, and takes charge of a mixed old city. A game hall riot case opened up the fig leaf of Guanghua Road - a hidden gambling hall, a shoe repairman with a scar face, a gangster boss with a hidden knife in his smile, and avengers who came back from the south. All forces secretly competed on the street. Zhou Yuan, wearing the white-washed police uniform, stood between the rules and the world. Some are wooing, some are testing, and some are threatening. He is just a small police officer, but he has control over what happens on this street.
