Having given up practicing law to teach (and drink), professor Markus Haglund wakes up one morning after a binge to find the attractive bartender from the night before in his living room. She is a student, Fia Jönsson, who had been trying to contact Markus about a potential case of a man falsely convicted of murder. Fia was asked by the murdered woman's daughter, being convinced her mother's boyfriend was not her killer, to help. With the aid of three other students, the team looks into police statements that seem to be incomplete or contradictory in hopes of re-opening the case.
