Sword of the Beast (獣の剣, Kedamono no ken, also called Samurai Gold Seekers[1]) is a 1965 jidaigeki film co-written and directed by Hideo Gosha.

[2] Set in 1857 at the end of the Tokugawa Shogunate, the story follows a fugitive samurai who has killed a counselor in his clan and is on the run.

Knowing that Gennosuke is a skilled swordsman, Gundayu makes the fugitive his partner in a scheme to poach gold from the shōgun's mountain.

Doing so is dangerous, because of the presence of bandits and other poachers in the area, as well as the risk of being caught by the shōgun's authorities and sentenced to death.

On the mountain, Gennosuke discovers another samurai, Jurota Yamane and his wife Taka, who are stealing gold as part of a mission for their clan.
