In late 1944, during the Lapland War, gold prospector and Winter War veteran Aatami Korpi lives alone in the remote wilderness of Lapland, panning and mining in search of gold. Eventually, his efforts succeed when he uncovers a rich gold deposit. Collecting a hefty amount of gold nuggets, Aatami sets off to deliver his gold to the nearest town. Along the way, Aatami encounters a 30-man Wehrmacht platoon led by ruthless SS Obersturmführer Bruno Helldorf and his subordinate Wolf, who are destroying settlements in their retreat and have taken dozens of captives with them. Though Bruno and the platoon initially take little interest in Aatami, they change their mind upon learning of his gold, and attempt to seize it from him. But unbeknownst to them, Aatami was a skilled fighter during the Winter War nicknamed "The Immortal", and their attempts to capture Aatami and steal his gold result in brutal clashes.
