Jiang Ye personally buried Lin Su in the ruins of the evidence collection site, thinking that she died in the explosion and was never involved again. Three years later, a serial murder case aroused public opinion. The familiar face in the dock was the witness Lin Su who should have died in the mud. She brought the blood-stained recording and the confidentiality agreement he signed back then, pointing out that he was the real mastermind behind the scenes. The police station files were burned and the evidence chain was broken. He was the only one who remembered the look in her eyes that night - not fear, but liquidation. Now she came back, not to seek survival, but to seek her life.
