In the city of "New Babylon", citizens undergo "memory stripping" surgery in exchange for absolute peace. Ling Su is the city's top memory keeper. Day after day, he seals the pain, ecstasy and love abandoned by people in the cold archives, while he himself is like an isolated island, floating in the vast sea of oblivion. Until one day, a memory marked as "extremely dangerous" - number 734, like a stone thrown into stagnant water, stirred up huge waves in his peaceful world. The woman Eve in his memory can actually "see" him. In order to explore the truth, Ling Su embarks on a dangerous journey upstream. What he will face is not only the dark core of the city, but also the deeply buried past that he himself chose to forget.
