The Box of Sun [La boîte à soleil]

In this silent, surrealist fantasy, thick clouds in a scorched sky prevent the sun from reaching the earth. Only a group of children in this gray world have access to a source of light which is in the wintry woods. They collect it into small boxes that they use to revive people imprisoned in pictures. A young woman grieving for her lost lover goes in search of these children so that they can bring her beloved back to life.
