Against the background of the Civil War, sixteen-year-old song-and-dance artiste Lotta Crabtree works her way across America, becoming ever more popular.
In London, August 1914, Austrian star Elsa Duranyi (Gertrude Michael) and English matinee idol Alan Barclay (Herbert Marshall) are in love and plan an immediate marriage. But the War comes and Elsa mysteriously disappears. Alan's ease in speaking German results in his appointment to the British Intelligence and, to aid his use as a spy, they announce he was killed in action. He takes the name and personality of "shell-shocked" Hans Teller, a German prisoner, and is sent into Germany on an exchange of prisoners.
"Lucky" Davis, a ladies-man and a devil-may-care U. S. Marine Sergeant, is leading a Marine-squadron on an expedition through a Phillipine jungle where an outlaw bandit is leading a guerilla-war rebellion. Their assignment is to rescue a group of children from an island mission that has been cut off from all communication. It comes as a bit of a surprise when Davis discovers that the "children" are a group of 18-25 year-old girls blissfully bathing in a pool while awaiting rescue.
