After getting out of Paris, Reginald, Lefort, Bouvet, and MacIntosh encounter Sister Marie-Odile, a nun whose order is secretly assisting the Résistance.

Bouvet and Lefort are sent ahead to Meursault to a hotel owned by Juliette's aunt, but there they almost run into Achbach, who has traveled there to interrogate Cunningham.

With Marie-Odile driving a horse wagon, the fugitives make their way to a shuttered gliding club, where they intend to use the gliders to reach the nearby Free Zone.

Closely pursued by Achbach, they manage to take off just in time, and a last-ditch attempt to bring them down with machine-gun fire is accidentally foiled by a cross-eyed soldier, allowing them to fly to safety.
