Jiang Che, the youngest son of the Jiang family who disappeared many years ago, returns to the family boxing gym and only wants to rest and recover from his injuries. Everyone mistakes him for a lazy good-for-nothing who cannot fight. Unexpectedly, eight boxing gyms join forces to challenge the Jiang family, destroy its signboard, and use the Jiang fighters' injury records to pressure them at every turn. As his father and brothers suffer successive defeats, Jiang Che is forced into the ring and finally stops hiding his true strength. Only then do they discover that this seemingly delicate and laid-back young master is actually the Masked God of Death who once swept the underground boxing arenas of Night Harbor. This time, he must protect the Jiang family while finally putting his pain and past behind him.
