War and women are the two forces pulling on Captain Flagg and Sergeant Quirt. During the First World War, Flagg waits for Quirt to train his recruits. In the meantime, Flagg spends his days wooing Charmaine, an innkeeper's beautiful daughter. When Flagg leaves for Paris to re-enter the fighting, the still-at-home Quirt takes a liking to Charmaine. What follows is a romantic triangle set against the backdrop of war, as Flagg and Quirt keep trading places until each discovers whom the other has been courting.
