In the cyberpunk city "Market City", memories can be tampered with and sold. While former memory cleaner 87 was forced to recall that he might be the real murderer of his wife, he also became the number one target of the MemCorp giant's shocking conspiracy "Project Ark."
Holding a deadly data chip in his hand and fleeing between neon and sewage, he must hunt for a mysterious cracker named "The Clockmaker" under the hunt of corporate agents and mechanical scavengers. When the memory cage in his mind is shattered, 87 must make a choice: retrieve the truth of the past, or tear apart the future of the entire city?
This is a desperate race in the ruins of memory, and the loser will be completely erased.
