The film opens with a rousing rendition of "The Deadwood Stage" - (Whip crack away) Then moves into Deadwood where we meet a clean and sober Wild Bill Hickok (Howard Keel) who treats Calamity as one of the boys. When a female entertainer Francis Fryer (Dick Wesson) is mistook for a female by saloon owner Henry Miller (Paul Harvey), Fryer is forced to perform in drag too much boos and cat calls.
Calamity takes it upon herself to go to Chicago to hire popular singer Adelaid Adams (Gale Robbins) to come to Deadwood to perfprm. In Chicago, Calamity mistakes Adams' maid Katie Brown (Allyn Ann McLerie) for her. Katie comes to Deadwood and becomes a hit when she performs as herself rather than an imitation of Adams. She becomes attracted to Lt. Danny Gilmartin (Phil Carey) but thinks that he is Calamity's man. Wild Bill meanwhile has developed a liking for Katie.
Calamity invites Katie to move in with her. Katie feminizes the unkempt cabin and the two women become friends. With the annual ball at the army fort coming up, Danny asks Katie to accompany him. She is reluctant at first but accepts. That leaves Wild Bill to take Calamity to the dance. But is dumbfounded when he see Calamity all dolled up for the first time. Anyway, all gets sorted out and the right peron winds up with the right partner and all leave happily ever after.
The characters of Hickok and Jane bear little resemblance to the real life characters so Warners took liberties in bringing the to the screen. For example, I don't think either of then got married and certainly not to each other. Day is outstanding nonetheless, Keel less so. Both get to sing mostly forgettable tunes as does McLerie except for Day singing "Secret Love", "Put 'em in a Box, Tie "em With a Ribbon" and "The Deadwood Stage".
In addition to Chubby Johnson who plays the stage coach driver Rattlesnake, there are several western veterans who pop up throughout the couse of the picture. Watch for Lane Candler, Budd Buster, Edmund Cobb, Franlyn Farnum, Glenn Strange, Robert Fuller, I. Stanford Jolley, Rex Lease, Tom London, Emmett Lynn, Kermit Maynard, Francis McDonald Gene Roth among others.
