Set in the late Meiji period in Hokkaido, Japan, Saichi Sugimoto (Kento Yamazaki) is a war hero who was known as Immortal Sugimoto during the Russo-Japanese War. He now starts a new life in Hokkaido. To raise money for his plan, he pans for gold in Hokkaido. He hears about the existence of gold nuggets that belonged to the indigenous Ainu people, but were stolen by a man known as Noppera-bo. Right before he was caught, Noppera-bo allegedly hid the gold nuggets. In prison, Noppera-bo tattooed the secret location among the bodies of 24 different prisoners. Each prisoner had a piece that would collectively reveal the location of the gold nuggets. Noppera-bo then escaped prison with those 24 prisoners. One day, Saichi Sugimoto is attacked by a wild bear. At that time, he is saved by an Ainu girl named Asirpa (Anna Yamada). Asirpa’s father was killed by the man who stole the gold nuggets and she wants to take revenge on her father’s killer. Saichi Sugimoto and Asirpa, for different reasons, begin to work together. More people join the chase for the hidden gold nuggets. Written by AsianWiki
