In the last days of the Wild West, the teenaged Six-gun Samurai is on his way east to find his father, his last known living relative. But as he travels across the untamed prairie, he finds himself tangled up with dangerous men and dark motives, forcing him to use his skills as a trick shooter and a swordsman to the utmost should he wish to survive. The Six-gun Samurai and his mentor Tetsuya travel across Texas on their way to find the boy’s father in St. Louis. But on the way, they run into a hotheaded girl named Annabelle Rose who is hunting for a gang of Japanese thieves who murdered her parents and left her for dead. Unfortunately, the girl wants vengeance now, and as far as she’s concerned, the fewer samurai there are around, the better.
