Set during the darkest days of World War II, King's Ransom tells the heroic story of Tsar Boris III, King of Bulgaria, and his extraordinary efforts to save his country's Jewish population from Hitler's concentration camps. Aware of the price he might pay for his risks, Boris faced the Third Reich with courage and resolve, firm in his Christian convictions that would not permit him to abandon nearly 50,000 Jews. Boris, along with members of the Orthodox Church, Jewish religious leaders, and others, ultimately ensured that no Bulgarian Jews lost their lives to Hitler's regime.

Based on a true story and historically accurate, Boris's quest to save Bulgaria's Jews is interwoven with the love story of Daria, the Jewish attendant to the Bulgarian royal family, and Dobri, a sergeant in the king's guard. With courageous characters and passionate storytelling, King's Ransom reveals how individuals acting on faith can change the course of history.
