In the early twentieth century, Russo-Japanese War veteran Saichi "Immortal" Sugimoto is drawn to the wilderness of Hokkaido during the gold rush, in search of gold to help support his deceased friend's widow. During his search, he stumbles upon part of a map, tattooed onto the bodies of criminals, that is said to lead to a stash of hidden gold. Teaming up with an Ainu girl who saves him in the wilderness, Asirpa, he sets off to find the gold, facing both the harsh wilderness and cutthroat criminals.
