On the isolated "Forgotten Island", the top memory restorer Shen Mo relies on data chips every day to reconstruct himself from yesterday. He can repair anyone's broken memory, but he can't piece together his own past before the "accident". When a mysterious woman code-named "Zero" appears with an unprecedented commission - "Create a love for me that has never existed" - the cycle of silence and tranquility is completely broken. In the process of constructing false memories for Zero, he discovers that his tampered past is closely connected to the ultimate secret of this isolated island. He must find his forgotten identity and the cruel truth hidden under the deep sea in the maze of memories that are difficult to distinguish between true and false.
