When seventeen others turned down the Unitarian Association's request for relief volunteers, Waitstill and Martha Sharp committed to the dangerous mission. "Defying the Nazis: The Sharps' War" is the story of their humanitarian work and the effect it had on their lives. The Sharp's left their two young children behind in Wellesley, Massachusetts and traveled to Czechoslovakia to aid refugees just as war was about to break out in Europe. While abroad, they combated political and social legislation, breaking laws in order to get imperiled individuals exit visas. From involvement with black market, money laundering, to the clandestine transportation of refugees, the Sharps played a vital role in the rescue of Jews and dissidents from persecution. The film features interviews with the refugees rescued as children, now adults, who were taken to America by Martha Sharp, and interviews with family members. These personal stories highlight the impact of social change and the effect of the Sharp's move to Europe during this turbulent time on their young children.
