A suspense novelist who lost his memory due to an accident returned home, only to find that the fictitious crimes he had written were perfectly reproduced in reality one by one, and he himself seemed to be the only murderer. Three months ago, he was seriously injured and lost his memory in a closed study. The scene was determined to be a suicide attempt. After recovering, he returned home and tried to resume his creation under the careful care of his wife. However, he discovered that the unpublished cases described in his novel manuscript—"Corpse Hidden in Vase," "Anchored on a Rainy Night"—were being played out in reality with astonishing accuracy. All the clues vaguely point to himself, and his closest wife, best friend, and attending doctor all seem to have their own secrets. Lin Mo must pry open the cage of memory and find out the truth before he finishes his latest book manuscript about the "perfect memory crime": is he a prophet who has insight into the crime, or is he the mastermind behind everything?
