In a near-future city where technology can accurately erase memories, the top "memory cleaner" Lin Mo is known for his calmness. He treats memories as editable data and eliminates pain for clients. However, when a woman named Anya came with a seemingly ordinary request - to erase the memory of her missing lover "Achen", Lin Mo's professional barriers collapsed. In the process of diving into the depths of Anya's memory, he not only discovered traces of artificial tampering in this memory, but also had a horrifying glimpse of his own long-forgotten fragments. He began to suspect that he was not only a memory cleaner, but perhaps also a deserter from his own past. In order to explore the truth, Lin Mo embarked on a dangerous journey upstream to pick up the fragments, and every awakened memory may push him deeper into the abyss.
