Set in the northern region of Tohoku during the eighteenth century and the reign of the eighth shogun of the Tokugawa shogunate, Samurai Hustle tells the story of the financially modest Nagaya clan. Lord Naito Masaatsu (Kuranosuke Sasaki( suddenly receives a demand from the shogunate to perform sankin kotai, a ritual visit to the shogun in Edo, within five days. If he fails to comply, the clan’s lands will be confiscated. This seems like an impossible mission as it usually takes six months to prepare for such a visit and eight days to travel to Edo. However, Masaatsu is determined to prove to the shogun that he can turn the impossible into the possible. Meanwhile, evil and greedy people working for the shogunate try to prevent his journey.
