A Polish spy working for the British during World War II is betrayed and compromised in Warsaw, leaving her no other choice but to descend into a dangerous world of treachery and deception in order to survive.

From his childhood in Poland to his adolescence in Nice to his years as a student in Paris and his tough training as a pilot during World War II, this tragi-comedy tells the romantic story of Romain Gary, one of the most famous French novelists and sole writer to have won the Goncourt Prize for French literature two times.
