In the "new ocean" of the near future city, memories can be edited and reshaped. Lin Zhou, the top "memory fabricator", shuttles through the depths of other people's consciousness every day, repairing wounds and erasing evidence of crimes, but he is still unable to mend his own heart that was broken by the unexpected death of his daughter. During an ordinary mission, he accidentally discovered a perfectly forged memory, and behind it was a shocking conspiracy that could subvert social order. In order to find out the truth, he was forced to join forces with the mysterious underground hacker "Echo" and step into the trap laid by the technology giant "Time Group". As he gets closer to the core, a more cruel truth emerges - his daughter's "accident" may not be an accident at all.
