The Samis aren't often portrayed in films. Not even in the Nordic countries, although their history has some similarities with that of the Native Americans.
Here it's Norway in the early 1850s. The church and the tradesmen sell booze to the Sami men, but unofficial ways of Christianity saves them. This is a threat towards the destructive order and there are counterattacks, which leads to the rebellion.
The script is a little naive and Swedish actor Mikael Persbrandt's overacting doesn't make it better. But the historical environment is well painted and conflicts like this one are very rare in movies.
