In the future urban "New City", memories can be stripped away and stored like data. Ling Zhou, the top memory stripper, uses his calm and precise scalpel to remove the painful past for clients. He is like a lonely ferryman, sailing in the sea of forgetfulness of others, but he is trapped by indelible memories. Until one day, a mysterious woman named Su Wan brought a bizarre request: what she wanted to strip was a "living" memory. This commission dragged Ling Zhou into a huge whirlpool composed of artificial intelligence, digital immortality and the boundaries of human nature. When the stripping knife touched the restricted area of memory, he discovered that some forgetting was more deadly than remembering.
