Jo Weisman, a young Jewish Parisian, and his family are taken by the Nazi Germans and Vichy France collaborators in the ''Vel' d'Hiv Roundup''. Anna Traube, a 20-year-old woman, walks out of the velodrome with forged papers; her mother and sister are captured. Annette Monod, a Protestant nurse, volunteers for the velodrome, and assists Jewish doctor David Sheinbaum. From the Vélodrome d'Hiver Jo's family and Sheinbaum are transferred to the Beaune-la-Rolande internment camp. Monod comes along. She does what she can to help the children, who are soon falling sick from the camp diet and conditions.
