An Englishman has a theory that accuracy is more important in a gunfight than speed or size of the ammunition. When he kills a bully with his specially designed rifled pistol, the Englishman decides he's ready to take on his goal - Bat.
Bat is having a good run at poker in Deadwood, South Dakota when the stagecoach arrives with the very proper Englishman Sir Edward Marion and his niece Elizabeth. As Elizabeth heads to the hotel for a cool bath, Marion enters the saloon for a drink where Bat is playing. His dress, style, and speech draw a crowd around him disturbing Bat's game and concentration. The bully Donovan during a conversation with Marion tries to draw him into a fight but Bat intervenes. After telling Bat he has an offer for him, Marion watches Bat play poker until he is free. Donovan still drinking, decides to break in forcing Marion into a fist fight with English rules and Bat as the referee which Marion wins easily. Afterwards, he shows Bat his single shot pistol with a long rifled barrel he made which he feels can win in any duel. Later, Donovan confronts Marion in the street where his long barrel lets him win. His next goal is Bat who in known for his skill with his pistol but Bat has a lesson for him. Written by
