Hillel Kook arrives in the United States at the beginning of World War II, fresh from the underground resistance to the British in Palestine. Under the alias Peter Bergson, he leads a small group of activists seeking aid for the rescue of Jews in Europe. Bergson is shocked to find his efforts blocked by both the Roosevelt administration and the Jewish establishment. Undaunted, Bergson and his colleagues organize a bold campaign in a desperate race against time and fear of reprisal.
