In New Victoria, memory is a commodity that can be stolen, traded, and tampered with. Lingkong, a top "echo thief" living at the bottom of the city, makes a living by stealing and selling other people's memories. He lived alone and only believed in the rules of survival, until during a mission, he stole a "native memory echo" that should not be touched.
In this chip, the broken consciousness of a girl named Ilara is imprisoned. Her memories, her fears, and her hopes flooded into Ling Kong's mind, dragging him into a deadly conspiracy. The technology giant "Yongyi Group" that controls the entire city launches a drag-net pursuit of him, vowing to recapture this chip that contains a shocking secret.
When the memories of two people begin to intertwine, and when virtual love collides with real crises, Lingkong is forced to make a choice: Should he erase this dangerous memory and return to a life in the shadows; or should he fight against the entire world for a girl who only exists in his own mind?
In this city built of lies, what he must recover is not only her past, but also his own forgotten heart.
