Because of the breakdown of his marriage with his wife Zhang Daichen (Xu Jinglei), the male protagonist Jiang Feng (Huang Bo) went to the Memory Master Medical Center for surgery. Unexpectedly, the surgery went wrong and his memory was overloaded by mistake. He inexplicably became a "murderer". The relentless pursuit of police officer Shen Hanqiang (Duan Yihong) made him gradually realize that the wrong memory in his brain was not only the key to solving the case, but also the only hope of redemption.
