Occupied France, 1942. Gilles is arrested by SS soldiers alongside other Jews and sent to a camp in Germany. He narrowly avoids sudden execution by swearing to the guards that he is not Jewish, but Persian. This lie temporarily saves him, but Gilles gets assigned a life-or-death mission: to teach Farsi to Head of Camp Koch, who dreams of opening a restaurant in Iran once the war is over. Through an ingenious trick, Gilles manages to survive by inventing words of "Farsi" every day and teaching them to Koch.

People prepared, lived, believed dreaming and waiting for this miracle - Christmas!
