A man is murdered on a remote riverbank, and a young woman confesses to the murder to the police that same night. Forensic psychologist Karla Eckhardt identifies the confessed perpetrator as Anna Lobrecht, whom she had classified as a compulsive liar in a report two years ago. It's possible that Lobrecht isn't telling the whole truth this time either.
