Link Stuart and Gauche are the ruthless co-leaders of a gang of bandits who rob a train of its $400,000 payload. On the train is the Japanese ambassador, on his way to Washington, who has with him a ceremonial tachi, a gift to the American president. Gauche steals the gold-handled sword and shoots dead one of the ambassador’s two samurai guards. At the same time, by Gauche’s order, other members of the gang double-cross Link by throwing dynamite into the train car he occupies and leaving him for dead. Before the gang departs, the surviving samurai guard, Kuroda, tells Gauche he intends to track him down and kill him, but Gauche is dismissive of the threat.
