Antoinette dans les Cévennes

"I" is Antoinette (Laure Calamy), an elementary school teacher, passionately involved with the (married) father of one of her students... When her lover cancels their plans for a romantic tryst to vacation with his wife on a multi-day hike in the footsteps of Robert Louis Stevenson's pioneering memoir Travels With a Donkey in the Cevennes, Antoinette makes a rash decision: she will make her own way to the mountains and surprise him on the trail. What could possibly go wrong?
