In September 1939, Webster is operating in an American hospital based in Paris. When France is threatened and occupied, despite the efforts of his aunt Nancy, Webster stays in Paris to help the resistance against Nazi occupation. Webster finds himself fighting on all fronts; for his own identity and freedom, for his lover Albert's freedom, and for those patients who, as of May 1940, are prisoners of war.

With the help of friend Henriette, a local French nurse, they begin a system of smuggling patients out of the hospital and beyond, all beneath Nazi noses.
