In a future where memories can be edited and deleted, top memory architect Lin Feng wakes up from a beach composed of data debris and loses all memories of himself. He finds himself stranded on an island composed of chaotic, fragmented memory fragments, surrounded by a "sea of oblivion" that is constantly encroaching on the land. In order to find himself and escape from this world that is about to collapse, Lin Feng must, like a detective, piece together these memory fragments that do not belong to him. However, he gradually discovered that this island was not a prison, but a cage he had built for himself. Every memory was a past he desperately wanted to forget.
