Xia Chen, a top forensic science student at Beijing Police University, was not only ruined by a well-planned injustice in his previous life, but also brought shame to his mentor, and eventually died in an "accidental" way while investigating the truth. With endless reluctance and regret, he was reborn and returned to the time when he had just graduated from college and was about to join the forensic department of the Shenshi Public Security Bureau. This time, he not only has the professional knowledge and painful lessons from his previous life, but also awakened a special ability - [Crime Retrospection], which allows him to "see" the crime scene from a first-hand perspective when he comes into contact with key evidence. His core goal is clear and firm: to take advantage of his rebirth, plan ahead, find out who framed him in his previous life, make up for all his regrets, climb to the top of the forensic profession, and put on the "white shirt" that symbolizes the highest honor.
