Have you ever thought that the painful memories you have forgotten actually went to a real place?
13-Year-old Lin Xiaotiao never thought that a pocket watch of unknown origin would tear a rift in his peaceful life. Starting from a rainy night, the school library will turn into the entrance of the "Memory Corridor" every midnight, a strange space condensed by all the forgotten pain, guilt and sadness of mankind. Here, rules are no longer rigid words. They breathe, grow, and even twist and mutate based on your inner fears. A rule "no reading in the mirror" may turn into "the pages in the mirror will swallow you up" in the next second.
In order to save his friends whose memories were erased by the "Forgotten" organization, Lin Xiaotiao and his young detective team - logic genius Chen Mo, perceiver Su Xiaomei, and mechanic Aji - stepped into this crisis. They will use childhood songs to fight against memory stripping in "Doll Town", and use emotions as bargaining chips to exchange for life in the "Deep Sea Memory Bank". They discovered that the villain "The Forgotten" was not trying to destroy, but was trying to eliminate all pain and create a painless "perfect" world.
However, the real terror comes not from the rules themselves, but from facing one's deepest wounds. Lin Xiaotiao must once again experience the fire that took away his friend's life when he was seven years old, and admit his guilt before he can grasp the true power of the pocket watch. When the world gives the ultimate choice of "forgetting the pain" or "carrying the memory", they will prove that it is those painful memories that make us complete people.
