Garrison is sent to rescue a German scientist who is working on the A bomb. But there's an air raid and the scientist is killed. Before dying he tells Garrison of something in a safe in the building that can help them figure out the bomb, but the building is being evacuated. Before leaving Garrison overhears a phone call calling for the bomb disposal unit because one of the bombs didn't blow up and it is by the safe. So Garrison grabs the two members of the unit and goes with them. While Casino tries to open the safe, Garrison tells the men to defuse the bomb but the one who knows how refuses. Another member of the unit agrees to, but he has only seen it done, not actually defused one.
