Appointment in Bray 1971

In 1917, the First World War is raging. Julien is from Luxemburg, so instead of having to go to war he studies piano in Paris. One day his friend Jacques, also a musician and now a fighter pilot on the front, invites him to spend a few days in his family's empty house in Bray. The housekeeper, a beautiful stoic woman lets Julien in, but his friend is late and he is obliged to wait. In the meantime, he starts reminiscing of the pre-war days spent with his friend and Jacques' girlfriend Odile.
