The skeletons deep in the green mountains uncovered a ten-year-old case. The forensic doctor Shen Tan held the copper key left by his father and deciphered the death code in the rotten texture. He thought he was already used to being alone until he met Detective Jiang Che - the man who always handed him a glove when the scalpel fell and pulled him out of the stench of corpses when he fell into obsession.
From the unknown corpses in Qingshangou, to the smuggling network that spanned many provinces, to the old anti-drug case involving two generations, they followed the clues paved by the bones. Shen Dao identifies the murderer's fingerprints under the microscope, Jiang Che protects his back in the hail of bullets; he uses a cold autopsy report to restore the truth, and he uses warm coffee to dispel the late night chill.
When Shen Zhen discovered that his parents' sacrifices were exactly the same as the serial cases in front of him, and when Jiang Che pointed his gun at his former mentor, those deeply buried secrets began to gnaw at people's hearts. The copper key opened not only the dusty wooden box, but also the tacit understanding between the two people that had never been broken - it turned out that some colleagues were destined to be each other's light in the darkness from the first time they handed over the gloves.
"You dissect your body, and I'll arrest my culprit. We each rely on our own abilities."
"Then don't always stare at my hands during my autopsy."
"... The hand is steady, suitable for holding a knife, and also suitable for..."
"Shut up, the autopsy is on."
The bones will rot and the fingerprints will be blurred, but every step they take together will be engraved in the temperature of the gun barrel and remain on the second button of the anatomy suit.
Intention: Use the bones as evidence to let the truth break through the ground, use companionship as light, and let the warmth be passed on.
