In the future city "New Sea" where memories can be read and repaired, Lin Mo, a top memory restorer, is like a soul diver, swimming in the deep sea of other people's broken consciousness. He is calm, lonely, and burdened with a past that cannot be repaired. When a mysterious woman named Su Qing appears with a seemingly simple commission - to retrieve the memory of a lost pendant - Lin Mo's peaceful life is completely shattered. He dived into Su Qing's seemingly calm but undercurrent sea of memories, only to find that the pendant was just the tip of the iceberg. Tampered footage, horrifying images that appeared out of thin air, and a "ghost of consciousness" chasing him dragged him into a deadly vortex of identity, truth and redemption. On the island of memory, every echo of the past is a symphony of life and death.
