In a future city where memories can be extracted, stored and traded, Lu Chen, a top memory custodian, lives a precise life in isolation from the world, sealing up the past that clients do not want to face. He thought his past was blank, until an anonymous memory chip with incomplete data broke his stagnant life. In the chip, a vague figure of a woman and a warm time that was forcibly interrupted aroused a strange and painful pain in his heart. In order to pursue the truth, Lu Chen embarked on a dangerous journey upstream, fighting against the giant organization "Dome" that controls memory technology, trying to piece together his stolen identity and the forgotten agreement.
