As the wedding reaches the ring exchange, Chen Mo suddenly rises from the guests and unfurls a wanted poster, pointing at the groom, Zhou Kai, a core member of the “White Shark” syndicate. The bride, Su Qing, is the informant he planted three years ago, and the only person who can testify against Zhou Kai. But Zhou Kai sneers and throws back a piece of evidence accusing Chen Mo of being the one who got away in the drug lord case years ago. The wedding turns into a showdown between police and criminals. Chen Mo is suspended, Su Qing disappears, Old Zhao offers him a poisoned drink from the shadows, and Captain Qin arrives with a secret order. As the truth is peeled back layer by layer, it turns out that the death of Chen Mo’s partner three years ago, Su Qing’s background, and Zhou Kai’s undercover operation all point to the same buried codename: the head of “White Shark.” Chen Mo must rally his allies again while wanted and hunted. This time, he won’t be alone.
