Ten years ago, a case of theft of cultural relics that was characterized as an "accident" resulted in the death of a veteran policeman and the unjust death of a museum researcher. Ten years later, police officer Shen Nanxing of the Crime Unit followed the clues of the serial thefts and caught the mysterious "shadow thief" Lin Qingyan.
He is a law enforcer, selfless, and carries on his shoulders the responsibility that his master paid for with his life; he is a prisoner, walking on the edge of the legal net, holding the truth about his father's corruption in his hands. Under the muzzle of the confrontation in the warehouse, an identical scar tore open a crack in the past, allowing the two opposing men to glimpse the scars under each other's armor.
When real evil is hidden in the shadow of the system, when justice needs the help of "criminal" hands to achieve justice, Shen Nanxing's gun begins to tremble, and Lin Qingyan's steps become hesitant. They exchanged secrets in the gap between black and white, and developed bonds in the pull of police badges and shackles. They knew it was a cliff, but they couldn't help but let each other get a glimmer of light.
"It's my duty to catch you." Shen Nanxing's voice was cold, but there was struggle hidden in his eyes.
"I'm waiting for you to bet that the scale in your heart is not stained." Lin Qingyan smiled lightly, but he held the key evidence tightly at his fingertips.
This contest that started with confrontation will eventually make them make the most difficult choice at the crossroads of law and love when the truth is revealed - whether to let him submit to the law or to walk side by side with him towards the bright road with cracks that no one has ever stepped on.
