Mie is a young woman with amnesia who is locked up in a secure psychiatric hospital. After Thomas Spectre goes missing, Detective Inspector Wolkers visits her, claiming that she was the last person seen with him -- making her a witness and prime suspect in the disappearance. As she appears to be the key to solving the case, the police won't allow Mie to be released from the hospital until Thomas is found. That means she has to reconstruct her lost memories and find her way through her recent past in a desperate attempt to fill in the blanks. But the more Mie remembers, the more she mistrusts the people around her -- and herself.
