Battle of Memories

Jiang Feng, a writer, underwent a procedure to erase some of his memories. At the memory center, there was an incident and he dropped his memory-restore-key card. He delivers divorce papers to his wife, but she refuses to sign the divorce papers until he restores his memories. After his memory restoration procedure, he finds himself in the mind of a serial killer. Feng goes to police with this information that he can see the murders being committed, but in those memories, he sees himself as murderer. At first, officers Shen Hanqiang and Lei Zi refuse to believe him, but after finding out similarities of his narration of crime scene and actual evidence they start believing his story. Feng realizes that killer has his memories and might try to kill his wife so he stages an escape but fails. At the police station his wife Zhang Daichen meets medical officer Chen Shanshan and befriends her. While officers wait for Feng's memories to provide a clue towards killer's identity, Lei Zi deduces that killer might be a woman who was best friends with the victim, pointing out that officer Chan might be the killer. Feng flees the prison to save his wife who is with Chan but instead disturbs his wife. Later it is revealed that office Shen Hanqiang is the actual killer who was using officer Chan to cover up his tracks. Shen kills Chan and as he tries to kill Feng, Daichen comes in between. Shen, having memories of Feng, can not shoot at Daichen. Lei Zi arrives at the scene and arrests Shen. Feng and his wife Daichen reconcile. ==Cast==
