Around the year 1000 AD warlike people, the so-called "tjuder", roam in northern Scandinavia. As they brutally kill a family in a remote area, including the parents and their little daughter, the family's teenage son, Aigin, observes the slaughter. He manages to flee from these killers and reaches a camp with other Sámi whose inhabitants are worried if he has been able to hide his track. Afraid of the murderous people, they decide to flee to the coast. The boy stays alone to avenge his family's murder. Unfortunately, they get him before he can do anything and force him to lead them to the other Sámi. He guides them but has a plan to destroy the barbarous people before reaching the camp.

During summer 1979, Ester moves to Alta in Northern Norway to begin teaching at an elementary school. Like many Sámi at the time, she is ashamed of her heritage and conceals her ethnicity. Ester goes to great lengths to fit in, even joining in with the derogatory jokes. When her cousin Mikkhal takes her to a camp by the Alta River, where people are demonstrating against the building of a dam, Ester learns how the fight for the river is also a revolt against the years of brutal racism and discrimination against her people. After a major confrontation with the police, Mikkhal and some other Sámi decide to go to Oslo to hunger strike in front of the Parliament. Knowing what is at stake, Ester realises it is time to make a stand…
