Each soldier heading for the front is conditioned to report to the mediums of the Spirit Corps when they die so the Corps can pass instant information about troop movements to military intelligence. Ginger and her fellow mediums contribute a great deal to the war efforts, so long as they pass the information through appropriate channels. While Ben is away at the front, Ginger discovers the presence of a traitor. Without the presence of her fiance to validate her findings, the top brass thinks she's just imagining things. Even worse, it is clear that the Spirit Corps is now being directly targeted by the German war effort. Left to her own devices, Ginger has to find out how the Germans are targeting the Spirit Corps and stop them. This is a difficult and dangerous task for a woman of that era, but this time both the spirit and the flesh are willing.
