Rita Hayworth and her fellow muses are enraged when they learn that Broadway hotshot Danny Miller (Larry Parks) is planning to spoof Greek mythology in his next play. Disguised as a mortal named Kitty Pendleton, Terpsichore decides to visit earth and use her powers to get a starring part in Miller’s musical. Before long, she convinces him to shift his attention from parody to serious art — but New York audiences aren’t so pleased with the resulting show.
