In the near future, a technology called "memory regression" is used in criminal investigations. But the protagonist is a rare patient with "reverse growth" (biological age goes back in time). His memory is reversed - he remembers the "future" but forgets the "past". When a serial murder case occurs and all the evidence points to him, he must rely on his chaotic and confusing memory to deduct the truth of the case in reverse and prove his innocence under the dual pursuit of the police and the real murderer.
