In the near future, memories can be precisely stripped away. Lin Mo, a top "memory weaver", is known for his calmness and precision. He can penetrate into other people's minds and cut out painful memories, just like a surgeon removing tumors. He regarded this job as the ultimate kindness until a woman named Xiaoman appeared. She asked to have her last memory of her late husband erased - a heated argument. When Lin Mo dived into that broken time, he discovered that there was not only sadness in the depths of his memory, but also a fatal secret and a crack that shouldn't exist. He must choose between abiding by professional ethics and exploring the truth, and this choice will not only determine the fate of his client, but also force him to face his dusty past.
