In this tender coming-of-age drama based on a true story, a Jewish boy finds friendship, camaraderie and safety in the shelter of a children’s hospital in Nazi-occupied France. In a lucky misfortune, young Maurice narrowly escapes a round-up of Jews in Paris, after breaking his leg in a dust-up with bullies. Whisked away in an ambulance, he watches helplessly as his family is arrested by French police. While treated for his injury, Maurice is diagnosed with tuberculosis and committed to a long-term-treatment facility in the suburb of Garches. Isolated from the outside world, he forms a close bond with the other boys of the ward. As the war intensifies, the hospital staff resorts to drastic measures to keep the children safe.
