The Germans threaten to turn the tide of war back their way with a new super-weapon, a guided rocket bomb capable of devastating vital parts of England. One of the rockets misfires on a test flight and lands in neutral Sweden intact. When the Allies learn that a Swedish underground group has retrieved the rocket, they enlist Gallagher and Komansky to clandestinely fly over to get it. They also procure a British rocket specialist, Group Capt. Carmichael, a former RAF fighter pilot. Unfortunately, the overbearing Carmichael bears a grudge against Americans because he was accidentally shot down by one, ending his flying career. Besides displaying anti-American hostility toward both Gallagher and Komansky, he drinks excessively, making him a potentially fatal liability as the team races a group of Nazis with the same goal.
