It’s 1942; the world’s at war.  In Hiram’s Spring, Nebraska, 10-year-old Sis fears for her brother, Danny, fighting Germans in North Africa.  Their small town helps the army build a B-17 bomber base.  Then, unthinkably, German Prisoners Of War are shipped into their valley, to work in their fields.  Sis meets Horst, a German POW, who seems friendly.  But is he friend?  Or foe?  Sis can’t decide.  Before it is over, the hatred war arouses will forever scar the lives of Sis, her brother, and the prisoner, Horst.
