Su Wan is the youngest genius forensic doctor in the Municipal Public Security Bureau. His scalpel is precise and neat, but his face has an inconsistent innocence. But recently, she began to lose her memory frequently, strange and bloody jewelry appeared in her drawer, and she even saw a figure exactly like herself at the crime scene. In the abyss of self-doubt, she met the sunny and passionate psychiatrist Lu Zhao, trying to find the truth through hypnosis. Little did they know that as the memory fragments were pieced together, her persona of "pure genius" gradually collapsed, and another cold and ruthless identity surfaced. When the secret of dual personality collides with the conspiracy of serial murders, Su Wan must distinguish whether it is the real herself in the mirror or the shadow that threatens her life before she destroys herself.
