Sonja Henie, Milton Berle, and John Payne star in this light hearted romantic comedy that features the Glenn Miller Orchestra as a struggling band named The Dartmouth Troubadours. The group is about to get its big break at a posh Sun Valley ski resort, when the romance between singer Vivian Dawn (Lynn Bari) and piano player Ted Scott (Payne) is shaken by a publicity stunt set up by band manager "Nifty" Allen (Berle). "Nifty" has arranged for Ted to adopt a war refugee, and Ted becomes responsible for a beautiful Norwegian (Henie) who decides she wants to marry him!

Nominated for three 1941 Oscars (Cinematography, Scoring of a Musical Picture, and Best Song: Chattanooga Choo Choo), SUN VALLEY SERENADE features the Glenn Miller hit "In The Mood", and of course, the dazzling skating of Sonja Henie.
