'Warrior' completes the story arc of Robert Matzen's 'Dutch Girl: Audrey Hepburn and World War II'. Hepburn's experiences in wartime, including the murder of family members, her survival through combat and starvation conditions, and work on behalf of the Dutch Resistance, gave her the determination to become a humanitarian for UNICEF and the fearlessness to charge into war-torn countries in the Third World on behalf of children and their mothers in desperate need.
