Fictional account of a time before World War II about two soldier friends and their families who start a non-violent organization called "The Last Crusade", based on Ivanhoe, to overthrow Hitler and return the world to peace before another great war starts. They receive worldwide support for their cause from 10 million people, elect the King of England's brother to act as their leader, and arrange for him to negotiate a peaceful agreement with the Third Reich. When Hitler refuses, German soldiers opposed to the Third Reich overthrow the government and appoint a peaceful leader. World War is avoided.
