In the future urban "New Island" where memories can be extracted, repaired and even traded, the top "memory weaver" Ling Su makes a living by repairing the broken memories of others, adhering to the professional bottom line of not prying or tampering. A mysterious commission dragged him into the abyss: a woman with the pseudonym "Echo" brought a memory that had been violently wiped out by man, leaving only the remains. When Ling Su sneaked into the ruins of this memory, he not only saw the horrific scene of a forbidden laboratory, but also discovered a shocking conspiracy that could subvert the entire social order of the new isolated island. This is no longer a simple repair job, but a deadly race against time, power and your own past.
