Indy (as Lieutenant Henri Defense) leads his Askari African soldiers to victory in an attack on an enemy stronghold and is promoted to Captain. His unit is sent across the Belgian Congo on an important mission, but most die of disease and exhaustion.

Being treated for a bee-sting to his toe, old man Indy recounts the time he spent in Albert Schweitzer's jungle hospital in Africa during the Great War. Schweitzer and his orderlies had picked up Indy and companions near death while attempting to bring a shipment of guns across the Congo. At first resistant to being treated by a German, Indy soon began to realize that Schweitzer was not interested in war, only attempting to cure people against all odds.
