Calamity Jane (Doris Day) is a western woman who dresses in men's clothing. She is the guard of the stage, and exaggerates how many Native Americans she has killed. She rescues Lieutenant Gilmartin (Philip Carey) when he is captured by Indians. She has a crush on him. Wild Bill Hickok (Howard Keel) has a thing for Calamity Jane, but would like her to wear woman clothes. Calamity goes to Chicago to recruit and actress, but gets the wrong woman. She comes back with the maid, Katie Brown (Allyn Ann McLerie) rather than the actress; but Brown she does the best she can. Calamity and Brown move in together, and Calamity get jealous when Brown and Gilmartin kiss. She is so upset she tells Brown she must leave. But Gilmartin really likes Brown. Hickok finally proposes to Calamity, and everything ends happy.
The voices of Howard Keel (baritone) and Doris Day are excellent and their singing really carries the musical. I especially like the song "The Black Hills of Dakota." They both sing with lots of energy. "I Can Do Without You" is also very fun.
