I'm being generous, I know, but consider the misleading 5.something score for this movie to be an anomaly. I first thought this was a 'Res Dogs' copy but it developed into a thoughtful thriller with enough plot to make it compelling. The absence of an obvious 'hero' figure is, perhaps, an obstacle to begin, but a strong ensemble cast contributes to maintaining interest in the conclusion of the movie. The question at the heart of the film, if there is one, may lie with the motivation of the Policeman, rather than the identity of the traitor. A genuinely classy European thriller of a type that can no longer be considered rare ( tell No-One, The Secrets...) but which is well worth a look.
