Xiao Ge, an ordinary white-collar worker in a financial company, has an unknown secret - he can sense the memory fragments of the deceased by touching the blood.
This superpower that had frightened him since he was a child completely changed the trajectory of his life the moment a murder occurred in the company.
When his fingers touched the blood at the scene, the fear and struggle of the deceased before his death, and even the face of the murderer, clearly appeared in his mind like a movie.
Veteran detective Jiang Haichuan was shocked by his "intuition" and urged him to join the special investigation team. Since then, this young man who once only wanted to live an ordinary life has become the police's secret weapon in solving crimes.
Serial killers, financial fraud, gang fights... Every drop of blood tells him the unknown truth. But as the case progressed, Xiao Ge found that he was involved in a larger conspiracy-someone was secretly observing him, waiting for the opportunity to close the net.
His childhood sweethearts were estranged because of his concealment, a mysterious female special police officer was secretly protecting him, and his former boss revealed his true face...
When blood is no longer just evidence, but the key to the truth, the city will usher in the rise of a legendary detective.
But in the battle between light and darkness, who will have the last laugh?
