In the wild-west Dakota outpost of Deadwood City, 1876, sharpshooter  Calamity Jane carouses with cowboys, townsfolk, and her rival Wild Bill Hickok.

After a mix-up in the planned talent for performances at the local  theater-saloon, Calamity goes to Chicago to fetch the glamorous musical star Adelaide Adams. But, she returns instead with Adelaide's maid, Katie  Brown, who has dreams of stardom.

While not a famous performer like  Adelaide, she turns in a performance that wins over the townsfolk. Calamity  offers to share her cabin with Katie. The two become fast friends. That is, until Katie wins the heart of Danny Gilmartin, a soldier stationed at the nearby fort.

Calamity, however, has had her heart set on Danny. Katie  charms Wild Bill who also sets his hat for her. The two friends, and strong  women, vie for the heart of Danny. At a local ball, Calamity sheds her  tomboy persona and blossoms as a lovely woman.

When Katie wins Danny,  a show-down between the two ladies electrifies the town. Calamity and  Katie, with help from Wild Bill, emerge from it as independent women of  honor, courage, and love.

Calamity and Wild Bill discover they love  one another and a double wedding is held for the two couples. The show ends with a reprise of “Secret Love'' by the entire cast.

The song won the  Academy Award as best song of the year when the movie of CALAMITY  JANE was released. The stage show is based on the movie. The song also  became one of Doris Day's major hit songs. Day portrayed Calamity in what  many consider her best role. Like the movie, the stage show is filled with  broad comedy, larger than life lead roles, delightful supporting character  roles, and a score overflowing with hummable, happy, and upbeat music.
