Three years ago, criminal investigation genius Chen Mo suffered a heavy blow due to an unsolved case. He lost all his memory and became an ordinary film police officer. After he solved many small cases by instinct, he was noticed by Su Jin, a trace expert from the provincial department, and transferred to the task force. Faced with seemingly perfect scenes, Chen Mo relied on his remaining tactile memory and logical intuition to restore the truth again and again. But whenever he gets close to a core secret, strange gaps appear in his memory, and psychiatrist Wei Ruomei, deputy director Han Yinghua, hacker Chu Yiming and others appear one after another with their own purposes. Chen Mo must find his peak in a series of intellectual games, and also find the past that was deliberately buried.
