Deity of dance Terpsichore (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.
