A bomber is killed in battle along with all of his companions; but something wakes in his dying, which is first a spirit bomber-crew, then the spirit of all those killed in battle, then the spirit of man, the cosmos and the Universal Spirit.
The story is arranged into eight chapters, each separated by an interlude. Stapledon focuses first on the rear-gunner of the bomber, but then as the initial part continues, the focus broadens to that of the crew and then includes everyone killed in the battle. It then precedes to cover the spirit of Man, but the broadening of the scope of the spirit does not continue, at times it splits apart, back down to the individual as the journey continues. The story is complex and can be difficult to follow at times. Yet in it are many of the same elements which made Stapedon’s other works so unique and timeless.
