In short, the movie tells a story of girl chosen to be the bride of god. Nothing much really happens, so I better not tell more, as just about anything would count as a spoiler.
Nenets people are still living on the Russian tundra, eating reindeer's and living in movable camps. They don't have much interaction with western civilization, and therefore one must not watch this movie as we watch our everyday movies and TV-shows. These people have barely heard of a movie, and their way of telling stories is completely different to ours.
