Inn of Evil (1971)

The story takes place in feudal Japan, when any commerce with the rest of the world was strictly prohibited. An idealist suddenly appears in an isolated inn (the one that the title refers to), the head-quarters of a group of smugglers, with stolen money intended to ransom his loved one who is forced to work in a brothel.
