In her second starring film, teenaged singing sensation Jane Powell plays Cheryl Williams, a 15-year-old music student who is led to believe that her older sister Josephine (Constance Moore) is a big Broadway star. In truth, Josephine is a stripper in a tawdry burleycue house, but fortunately Cheryl (apparently) never reads any out-of-town newspapers and thus is in a state of blissful ignorance. The fun begins when Cheryl arrives in New York, figures out the truth, and tries to marry Josephine off to big-time Broadway producer Arthur Hale (Ralph Bellamy). As a result, both Josephine and Cheryl are starring in Hale's latest production. Yes, it's a Deanna Durbin picture without Deanna, right down to newly arranged versions of old operetta favorites. Delightfully Dangerous is currently available from several video companies thanks to its "public domain" status.
