West and Gordon take on a band of counterfeiters who have robbed the mint of plates used to print money.

After his friends Mr. Cousin is wounded and Mr. Brother is killed, Earp goes after the people who did it. He learns they are the four members of the Dry Gulch Gang who attacked a supply train for the Cheyenne Indian reservation.

The stage arrives with the driver shot and $5000 of new silver dollar coins stolen. The driver gives Earp details about the robbery but they turn out to be false. Upon his return Earp finds the driver shot dead at the doctor's office.

Earp meets a man on the stage that treats an injured couple after a collision. Earp and Dr. McCarty who is impressed by the man's work urge him to open a practice in Dodge City but when smallpox breaks out they learn he isn't licensed.

After Bat's shirt sleeve is hit by a bullet from a gunman Earp had hit in the shoulder, Mayor Kelley tell Earp he must shoot to kill. Earp is later forced to kill a man which causes him to have second thoughts about his job.
