Wanghuan, is a veteran assassin who has an important mission: To eliminate the head of the Lin Group. Just as he is about to kill his main target, the daughter of the boss suddenly appears and by reflex, Wanghuan shoots her. In revenge, the boss of the Lin Group responds with a shot but misses. Although Wanghuan manages to kill his target, his informant tells him that killing the girl caused the mission to fail and that his service would no longer be needed, but the truth behind all this is that his informant Liyue had set him a trap, and as a result Wanghuan is killed by him… Or was he?
