In the "New Arc" of the future city where memories can be edited, deleted and transplanted, Lin Mo is the industry's top "memory weaver". He is calm and precise, and regards memory as a malleable code, erasing pain and weaving happiness for his clients. However, due to an unexpected operation, a fragment of memory that belonged to no one - a woman's desperate last words on a rainy night - was imprinted in his mind. This fragment erodes his proud rationality like a virus, forcing him to embark on a dangerous journey to pursue the truth. He gradually discovers that behind the skills he relies on for survival, there is a secret that can subvert the order of the entire city, and his own forgotten past is the core of this secret.
