Hello. This is my first post on this board, I'm searching for a movie and I can't seem to find it...

It's a Norwegian movie about a prison colony (for teenagers if i remember correctly) on an island in the beginning of the 20th century. I remember correctly, there were 'revolts' and some of them even tried to escape but failed to do so. I watched it like 2 years ago and I wouldn't mind watching it again.

Thanks in advance.
