She swore, drank and shot like a man. Cowboy hat glued to her head, gun in hand and cowboy boots on her feet, she attracted the respect of those who met her. She was a legend of the American West ... Her name was Calamity Jane. Southern girl, the young Martha Jane Canary goes hunting with the men, but at 16 she was orphaned. After two years of wandering, she joined General Custer as a scout. There she made ​​the campaign against the Indians of Arizona. During a battle, she returns safely to the general camp, who named illico Calamity Jane.

The years that followed, she carries out missions, often risky: she crosses a river by swimming, enters the Indian tribe of the Black Hills, conveys cattle from California to Wyoming, Oregon travels, or chasing the murderer of her dear friend Wild Bill. In 1885, having had enough to ride, Calamity Jane marries, runs a hotel in Colorado and became a mother. After the departure of her husband, far from being removed, she works for the Palace Museum in Minneapolis and participates in shows touting the American West, then in vogue.

His life is already a legend, when weakened by illness, she died at the age of 51. Since then, her  body is buried next to Wild Bill, Deadwood Cemetery, one of her last wishes.
