A rootin', tootin' shootin' hoyden in the western town of Deadwood, Calamity Jane spends her time cussing out Wild Bill Hickok. Jane promises the citizens of Deadwood that she can persuade classy Chicago stage star Adelaide Adams to perform at the local opry house. Through a case of mistaken identity, Jane brings Adelaide's maid Katie back to town. Katie proves to be a success all the same, and out of gratitude promises to make a 'lady' out of Jane, who is sweet on handsome Lt. Gilmartin. When the lieutenant chooses Katie over Jane, our heroine is heartbroken - until she realises that she has loved Wild Bill Hickok all along, and that the feeling is mutual. The peppy musical score by Sammy Fain and Paul Francis Webster includes the Oscar-winning Secret Love, which became a million-selling hit for Doris Day.
