A V-1 rocket crashes in Sweden. The allies want to get it. They recruit a rocket expert Group Captain Anthony Carmichael. Carmichael is in civilian clothes in the Star & Bottle and he and Sandy have a tiff. Sandy finds him drunk later passed out on a bench. On the mission, Gallagher, Carmichael & Komansky fly to Sweden in an unmarked plane. They have engine trouble and the compass fails so they follow a German plane in. The German plane is a diplomatic courier which carries the designer of the V-1 guidance system, Dr Tanzman and Oberst Ulrich. They are also there to retrieve the rocket as well. Carmicheal drinks too much and reveals his mission to Swensen, a German operative.
