In the dark night, some people go further for the light.
Zhao Ming, a gangster who has been at the bottom of Jiangcheng for many years, was supposed to disappear during a gang purge, but was accidentally selected by the police and became a "hidden line" lurking inside the gang.
During the day, he is an unknown number in the police files; at night, he is a trusted brother in the underground world.
Every time you deliver a message, you are dancing on the edge of a knife.
And when he discovered that the target he was pursuing actually involved senior police officers, former comrades and blood relatives, Zhao Ming began to understand that the real enemy may never be in the dark.
In Jiangcheng, a city where lights never sleep, everyone has a secret.
He lives in the cracks of lies, just for that little bit of truth.
But when black and white are blurred and good and evil are out of focus, how can he hold on to the bottom line?
——"Some people are destined not to see the light, but they themselves are the light."
A secret war about trust, betrayal and redemption is about to begin.
