The Germans have surrounded a secret atomic research facility with a prison camp full of high profile POWs, believing the Allies will never bomb for fear of a major public relations fiasco. The Americans have an ace up their sleeve, however, in the person of Colonel Harry Connelly, a wizard at pinpoint precision bombing with 43 successful missions under his belt. But, unbeknownst to his comrades, Connelly is feeling the fatigue from so many crucial missions, and his first attempt ends in the very tragedy the Germans had foreseen, causing him to crack under the stress. Gallagher steps in to try again, but he lacks the training and experience Connelly had, foreshadowing a disastrous repeat of the previous effort.
