Saunders' squad is assigned to escort Sgt. Keeley of the Signal Corps on a special scouting mission to find an enemy location that cannot be spotted by aircraft. Sgt. Keeley uses pigeons he has trained to fly over enemy positions while carrying a small camera, and then return to their mobile roost with the pictures. Keeley is unfriendly from the start, and as the squad escorts him into enemy territory and they become involved in several firefights, Keeley clearly shows he cares only about his pigeons - not his fellow GIs.
