Evert Backstrom is a rock star among cops. Starring as a TV expert doesn't help his ego or reputation. He thinks he's a genius, and he is, at solving crimes. When a woman's skull is found, it seems she was murdered recently, but DNA points to her death in the 2004 tsunami. Prosecutor Hanna Hwass believes it's a mistake, but Backstrom sees a case only he can solve: a woman who has died twice.
