Can a documentary be a delicious and scandalous police procedural? It can. Investigating Judge Anne Gruwez gardens with her white rat, rides through Brussels in a vintage Citroën, only to arrive at an office where she investigates horrid homicides, dominatrixes, and cold cases which she reopens with the help of two police investigators descended straight from central casting of crime series. Directors Jean Libon and Yves Hinant touch this delicate subject with neither solemnity nor excessive voyeurism. Behind the humor of the characters and the shock value of the cases themselves, however, hides a meditation on the need for a humanistic, emotionally intelligent approach to justice.
