The city that never sleeps, filled with wine and wine, hides an uneasy haze. Under the seemingly prosperous and peaceful K City, there is such a dirty underground city hidden.
As the most outstanding graduate of the police academy, Wen Da was selected to participate in the undercover operation set up by the K City Police Department to eliminate BLADE, the largest underground black market. His younger brother Wen Xin, who he had a crush on for a long time, joined the special operations team as a forensic examiner.
"Are you kidding me? Are you a cop?!"
"Do you want to drag him into the water? Wen Da!"
As the case continues to advance, more secrets surface, and the unknown side of the police station is slowly being unearthed.
"It's me, I'm the undercover. It has nothing to do with him... My name is Liang Qi, and I'm the police."
"Welcome back, my honey."
