After a near-death experience during an undercover investigation, police officer Wu Yu is transferred to a new district where he can continue fighting crime under a lower profile. But keeping the city safe doesn't come easy when he is constantly at odds with Captain Bu Chonghua, his superior in the force who desperately wants him gone. The head honcho may not be impressed with his blasé attitude, but Wu Yu learns that there is more to Captain Bu than meets the eye as the two embark on a series of drug busts, murder investigations, and even cases involving the supernatural. While foiling sinister plots and uncovering dangerous secrets, together, these total opposites must put aside their differences in the name of justice, and perhaps they'll find common ground along the way.
