Europe's Thirty Years War from 1618-1648 is widely known as a religious war between the Catholics and Protestants, but certainly included groups that together were called "Anabaptists" (meaning rebaptizers) by their enemies. This religious war was so bloody that it helped drop Germany's population of 15 million in 1600 down to 10 million by 1650. Set in 1675 with their world on the upswing, Heinrich and Ada Mann are strong believers that live in the country outside Herrenberg, Bavaria (Germany). Because of their firm stand and obedience only to the God of the Scriptures, they realize severe persecution may be "just around the corner." Although concerned for the future of all their children, the Manns are most concerned about their oldest son, Ernest. Will Ernest accept the Christ as his Savior and be baptized, knowing the probable consequences of a true believer?
