Memories can be edited, cut and deleted just like data. Ling Su is the top expert in this field. He can sneak into the depths of other people's most painful memories, erase them without trace, and bring false peace to his clients. However, Ling Su himself is imprisoned by a past that cannot be erased. In a seemingly ordinary mission, Ling Su discovered a piece of "ghost data" in the memory of a billionaire that should not exist - the horrified face of a girl. This discovery was like a crack, allowing him to glimpse the shocking conspiracy behind the "Yongxi Technology" he worked for. They are not deleting memories, but harvesting mankind's most extreme fears. In order to explore the truth, Ling Su must violate all rules, sneak into the forbidden area of memory, and face the nightmare deep in his heart. He will discover that the real prison is not memory itself, but the price of forgetting.
