Evil in the form of an unknown shaman divides a small community of Inuit. Twenty years later, two brothers emerge to challenge the evil order: Amaqjuag, the Strong One, and Atanarjuat, the Fast Runner. Atanarjuat wins the hand of the lovely Atuat away from the boastful son of the camp leader, Oki, who vows to get even. Oki ambushes the brothers in their sleep, killing Amaqjuaq, as Atanarjuat miraculously escapes running naked over the spring sea ice.
