In Hanhai City, where technology can accurately erase memories, Shen Mo is a top "memory cleaner." With the calmness of a scalpel, he cuts off the painful past for his clients, while he himself is like an isolated island, isolated from all emotions. When a woman named Lin Wan came and asked to erase an extremely precious memory of love, the silent professional creed was shaken for the first time. In the process of exploring this memory, he accidentally came into contact with a dangerous secret that had been deliberately buried. He discovered that forgetfulness is not a merciful antidote, but fragments of memory may be the only path to truth and redemption. This time, he is no longer the eraser of memory, but the guardian of the truth.
