Dr Leo Benedikt is a forensic psychologist. He deals with what goes on in the minds of mentally abnormal lawbreakers. It doesn't matter whether Cara Horvath calls him in as an expert for the police, or whether someone asks him for help in a private case: Leo knows that every crime starts in the psyche - and therefore can only be solved there. As he investigates a series of mysterious suicides, he stumbles across the mysterious pharmaceutical company Janus - and is stunned to discover what is actually behind the suicides.
