In medieval Finland, the Sami – a tribe of peaceful hunter-gatherers – struggle to survive in a frozen wasteland. Aigin (Mikkel Gaup), a young Sami, watches in horror as his parents and sister are brutally murdered in a surprise attack by the Tchudes, a rival tribe of violent nomads. Though Aigin flees to safety, the Tchudes follow his tracks to another encampment. Abducted and forced to comply with Tchude demands, Aigin feigns weakness – while secretly planning his own shocking revenge.
