Twenty-six-year-old Lin Nian was fired by the company for "illegal use of AI", which she denied. Lawyer Lu Ci handed over a crumpled business card: "Don't reconcile, I will nail them to death." She didn't know that this dismissal was just a prelude. A machine that can read human consciousness, a memory that does not belong to her, a person who has been missing for twenty years - all the truth points to the secret that was implanted in her brain when she was three years old. She doesn't take anyone's side. She's on her side.
