There are many serious cases in Jiangcheng, and old records are hidden in the abyss.
Forensic doctor Su Wan returns home just to investigate the 713 arson case in which his father was wronged.
Broken corpses emerged and old marks were revealed. She and the criminal investigation team leader Lu Zeyan used the evidence as a tool to pursue the murderer.
Old cases have not been resolved, and new cases have arisen. Every scar hides the unspoken truth, and every file is connected to a deeper darkness.
They don't just solve an old case, they tear open an entire city's hidden abyss.
They are strong partners fighting side by side, and they are half a step behind each other.
In the name of forensic medicine, we uphold justice in the world.
