While I agree I was expecting a more visual story from the synopsis, I strongly recommend the movie "The Hunt" with Mads Mikkelsen to get a feeling of what he may have gone through. It's a really good movie.
It's actually one of my favourite movies from the last few years. But that story is very different, at least because he's accused by the children themselves, whose parents happen to also be his closest friends. Anyway, really excellent movie.
