The year is 1945. The war is over and 21-year-old Betty Lake has been invited to Europe to sing in a USO tour for American soldiers who now occupy Hitler's Germany. The first nights performance is a hit. Betty becomes enthralled with the applause, the former Nazi-held mansion they're housed in and the attention of Frank Witt, the US Army Signal Corp Photographer. Yet the next night this songbird is ready to fly the coop when Betty's dear friend, Kat, turns up missing. Betty soon realizes Frank's photographs could be the key to finding Kat. Betty and Frank team up against post-war Nazi influences and the two lovebirds' hearts may find the answers...in each other.
But will they have a chance for their romance to sing? The truth will be revealed under a German moon.
