Trailer (foreign) for Sword of Desperation.
The story begins with a murder: Sanzaemon suddenly, if very politely, kills the favored concubine of his lord, Ukyo. The deed looks like betrayal, but the killing was meant to end the woman's destructive influence. Sanzaemon is sentenced merely to a year of house arrest, during which he falls in love with his late wife's niece. Ukyo is prepared to wait for revenge, and ultimately Sanzaemon must fight for his life, using his trademark "sword of desperation" gambit.
