Something nefarious is afoot in the 918th. Stricken by a series of mechanical mishaps that have already cost several planes, Gen. Savage's group is tasked with ferrying a beautiful spy to a parachute drop over Nazi-occupied Poland. Once again, the bomber assigned the mission is struck by gremlins that bring her down with the loss of a popular pilot and co-pilot, but the spy survives for another try. With this latest disaster, tensions between the air crews and ground crews explode into mayhem. But evidence starts to appear that indicates the miscues may not be accidental, and suspicion runs rampant through the base, endangering the spy's mission and the confidence of the troops.
