In the "Mirror City" where memories can be repaired, tampered with and traded, Lin Ci, a top memory restorer, can piece together anyone's broken past, but he can't recall the face of his deceased wife. A mysterious commission involved him in a conspiracy that spanned several years. The client, Helian Shuo, a powerful man, asked him to verify a memory about a murder. When Lin Ci dived into that bloody memory, he was horrified to find that the victim in his memory was exactly the same as his deceased wife who he thought about day and night. In pursuit of the truth, Lin Ci steps into a maze of lies and memories. Every step he takes may bring him closer to the truth, or may make him completely lost.
