Criminal investigation team leader Lu Yetang solved a serial corpse case. The murderer in the surveillance video had the same appearance as him, including the scar on his left eyebrow. When the evidence pointed to the unsolved disappearance case ten years ago, the suspect he arrested was actually the psychologist Jiang Yao who personally sent him to rehab. Jiang Yao smiled and said, "You forgot, it was you who pushed me off the bridge that night." And in Lu Yetang's mind, images he had never remembered before emerged - blood, guns, and an identity buried by his own hands. After ten years of reincarnation, who is the real criminal? The truth is hidden in the forgotten part of Lu Yetang's memory.
