Write a synopsis for a psychological thriller that utilizes a non-linear timeline. The story should be told from the first-person perspective of an unreliable narrator suffering from anterograde amnesia. Structure the synopsis into three distinct segments: The Middle (the discovery of a crime), The Beginning (events leading up to the crime), and The End (the resolution). Ensure that details in the later segments contradict the narrator's perception in the earlier segments, revealing the true nature of the events only at the very end.
