In Xinhai City, a future city soaked in neon and acid rain, memory has become a commodity that can be extracted, traded, and even tampered with. Lin Mo, a former memory architect whose future has been ruined, is now a "memory recycler" wandering in the gray area, making a living by salvaging broken memory fragments. A mysterious commission involved him in a huge conspiracy: a woman named Su Wan asked him to retrieve a completely erased core memory of her deceased father, Su Zhe, the founder of "Eternal Life Technology". As Lin Mo dives into the dangerous sea of memory, he discovers that it is not only related to the secrets of a family, but also touches upon the technological cornerstone on which the city relies, as well as the ultimate definition of human emotions and existence. He must make his own choice between the forgotten truth and the cold reality.
