Om zijn krijgers voor te bereiden op mogelijke aanvallen van buitenlandse indringers, organiseert de hanshu een marathon. De marathon volgt ongeveer 58 kilometer een bergpad. Reservisten doen mee aan de marathon en krijgen een prijs aangeboden. Ondertussen wordt de marathon door de centrale regering van Edo ten onrechte als een daad van verraad beschouwd. De moordenaars worden naar Hanshu Palace gestuurd. Jinnai Karasawa (Takeru Satoh) verschijnt als een normale samoerai, maar hij is eigenlijk een spion voor de centrale overheid. Hij realiseert zich dat er moordenaars naar het Hanshu-paleis worden gestuurd. Om de moordenaars tegen te houden en het misverstand uit de wereld te helpen, gaat Jinnai Karasawa wanhopig op de vlucht.
Nee, helaas is Samurai marason nog niet beschikbaar op Netflix in Nederland.
