Per its title, this merry Warner Bros. musical was filmed on location in the resort community of Agua Caliente. Pat O'Brien plays magazine editor Larry MacArthur, whose scathingly negative review of tempestuous dancer La Espanita (Dolores Del Rio) has incurred the lady's considerable wrath. Through a fluke, MacArthur finds himself in Caliente, where he begins ardently pursuing the lovely Rita Gomez, not realizing -- at least at first -- that Rita and La Espanita are one in the same. Intending to humiliate MacArthur, Rita relents when she realizes she's fallen for him as well. Of the supporting players, only Edward Everett Horton is given any worthwhile material, and he makes the most of it. The Busby Berkeley dance numbers are okay, but the film's musical highlight is Wini Shaw's rendition of "The Lady in Red," followed by Judy Canova's semi-parody version of the same tune.
