In the near future where memories can be extracted and sealed, Lin Mo, a top memory planner, peels away pain for clients with scalpel-like precision. He abides by the rules and lives a stagnant life until a woman named Chen Qing breaks in and accuses him of "murdering" her father's memory ten years ago. A dusty key and a forbidden project called "Sea of Oblivion" dragged Lin Mo into an elaborate conspiracy. In order to pursue the truth, he had to take the risk and dive into the depths of his sealed memories about his sister's death. There, he discovers that every forgotten moment may be the only path to hell or salvation.
