The play is heavily metatheatrical, being not only staged at but also set at the Ambassador Theatre, the actors playing actors appearing in a play at the Ambassador. This play-within-a-play concerns a strategic bombing squadron; the squadron commander frequently steps out of character to reassure the audience that they are only watching a play. This conceit is carried to the point where the actors themselves exhibit confusion over whether they really are actors playing airmen, or actual airmen. For instance, in the second act, Henderson (played by Ron Leibman) is scheduled to be killed -- he knows this, being familiar with the script, and is not worried; but then later, a corporal is killed on a mission and Henderson is unable to find him offstage. Henderson worries that the corporal really has been killed, and that perhaps the "play" is reality.
