I can't remember the name of this movie but I'd love to watch it again. It's been a while since I've seen it so I don't remember much. The movie is in French but with English subtitles.

Woman's husband goes off to war and doesn't come back. A young man (16 or so) comes by and ends up staying with the woman to help in exchange for housing. They fall in love. There is a scene where they are walking through a field (?) and planes fly over and start dropping bombs.

Not sure if that's enough?
