In a German prison camp in World War II, undiscovered by the guards, some Americans built a homemade radio. One day news came that the German high command had surrendered, ending the war. Because of a communications breakdown, however, the guards did not yet know this. As word spread among the prisoners, a loud celebration broke out. For 3 days, they sang, waved at guards, and shared jokes over meals. On the fourth day, they awoke to find that all the Germans had fled. Their waiting had come to an end.
