Jagten aka The Hunt (2012).
Danish film where Mads Mikkelsen plays a man in a small close knit community, separated from the mother of his son, with an adorable dog. He is falsely accused of sexually abusing a girl at the nursery where he works. Guess what happens?
Yeah it's a bit by the numbers but it's pretty realistic (I know one person who went through this sort of thing and it replicates the situation rather well).
It contains hunting scenes and real dead animals so if that sort of thing upsets you to the point where you would rather not watch the film be warned. It is beautifully photographed and the performances all round are remarkable, especially the child performers but I would prefer not to have watched it because like bkev these sorts of stories just make me tense up and feel rotten no matter how well they are made.
