13 year old kind-hearted Sonja arrives at a tiny village together with a company of bandits. But there is a curse on the village. A long time ago, the King’s only daughter Goldhair disappeared while searching for the Christmas Star. The Queen died of a broken heart, leaving the shattered King all on his own. From that day on, the King cursed the Christmas Star, thereby causing darkness and grief to descend upon the land. However, an old sage has revealed that Goldhair is still alive, and will return only if the King finds the way back to the Christmas Star. Ever since, the King has been searching for the Christmas Star every Christmas, but all in vain.

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.
