The world isn’t simply black or white. Most of it lies somewhere in between. Everyone has both good and evil within them. Faced with different choices, some become demons in an instant, while others turn into heroes for a few seconds. The serial murders committed by the “Dark Vigilante” in Binjiang City have left numerous police officers facing impossible choices. The head of the criminal investigation team is also beset by doubts about whether he has a split personality. The team’s three stalwarts solve one bizarre case after another while matching wits and courage with this mysterious vigilante. Who is the hidden hand behind this grand scheme?
There are no messy romantic subplots, just pure crime-solving, which is great. It's just that Ma Tianxiao is quite a tragic figure; he's a complex character, both righteous and evil, and ultimately sacrifices himself. Perhaps this is the best ending for him.
