Ten years ago, an artifact theft dismissed as an “accident” left an old policeman dead in a blaze and a museum researcher falsely accused and dead. Ten years later, Major Crimes officer Shen Nanxing follows the clues in a string of robberies and locks onto the mysterious “Shadow Thief,” Lin Qingyan.
He is a law enforcer, impartial and stern, carrying on his shoulders the duty his mentor gave his life to pass on. He is a prisoner, walking the edge of the law, holding in his hands the truth behind his father's disgrace. At gunpoint in a warehouse, an identical scar tears open a crack in their past, letting the two adversaries glimpse the wounds beneath each other's armor.
When true evil hides in the shadows of the system, and justice can only be served with the help of a “criminal,” Shen Nanxing's gun begins to tremble, and Lin Qingyan's steps falter. They trade secrets in the gap between black and white, and their bond deepens as badge and shackles pull them in opposite directions. They know the edge is a cliff, yet can't help turning a sliver of light toward each other.
“I'm arresting you because it's my duty.” Shen Nanxing's voice is cold, but his eyes betray his struggle.
“I'll wait for you, betting that the scales in your heart haven't been corrupted.” Lin Qingyan smiles faintly, but his fingers tighten around the crucial evidence.
The contest that began in opposition will reach its end when the truth comes to light, forcing them to make the hardest choice at the crossroads of law and loyalty: let him face justice, or stand beside him and walk a fractured road to the light that no one has ever traveled.
