Plot
With the end of the American Civil War, military industrialists are left with an oversupply of weapons. Some of the more unscrupulous ones view the Indians as possible new customers.

Wild Bill Hickok has just been discharged from the Union Army and is making his way back west. On a paddle steamer, he bumps into his old army scout colleague, Buffalo Bill Cody and his new bride. Later, their mutual friend Calamity Jane is the driver of their stagecoach to Hays City, Kansas.

John Lattimer, an agent for unscrupulous gun makers, has supplied the Cheyenne with repeating rifles, which enable them to kill half of the troopers at a United States Cavalry outpost. Hickok discovers the rifles and reports it to General George Armstrong Custer. Custer sends out an ammunition train to the fort with Cody as guide. Hickok tries to locate Yellow Hand, the leader of the Cheyenne, to find out why the Indians have gone to war.

When Calamity is captured by the Indians, Hickok tries to bargain for her release, but is taken to Yellow Hand (as he had hoped). Yellow Hand states that the Indians are fighting because the white man has started settling land promised to the Indian and is killing off the buffalo. Yellow Hand promises to release his captives if they tell him the route of the ammunition train. After much prodding from Calamity, Hickok professes his love for her just before he is about to be burned alive. Calamity then discloses the route in order to save Hickok. Yellow Hand holds true to his word by releasing his two prisoners.
