Der Staat gegen Fritz Bauer

That's metaphorically and literally speaking of course. One might also add that it can be a pun too. But while my summary line is definitely on the light side, the movie is not. And it couldn't be with the story it wants to tell. Germany has an obvious history with Nazis and the subsequent hunt for them. Or sometimes neglect in hunting them down for various reasons.

This movie shows one of many cases and one man who was determined to bring as many to justice as possible. Despite and through all obstacles that were before him. So this is a story (thriller) that has quite a bit going for it. It's really well made and well acted too and the suspense is there, from the start until the end. There's also a lot of award talking going on about this, if that is something you're interested in
