In the future city, memories can be read through echo systems. Merlin, the top memory stalker, is responsible for sneaking into the last memory fragments of the deceased to find the truth of the crime. When he was ordered to investigate the bizarre suicide case of genius scientist Dr. Evelin, he discovered an unexplainable moment of fear in the echo of her memory that did not belong to her. This tiny crack dragged Lin Mo into a huge whirlpool. He discovered that what he was searching for was not only the truth about a murder case, but also the ultimate torture about the reality and existence of memory. And behind that cold wall of echoes lies a silence that can overturn the entire world.
