In a small town in WWII France, a German officer is billeted in the house of an elderly man and his niece who resist the occupation by refusing to interact with him, even as he speaks to them candidly about his life and hopes for the future of France and Germany.

Elisabeth and her brother Paul live isolated from much of the world after Paul is injured in a snowball fight. As a coping mechanism, the two conjure up a hermetic dream of their own making. Their relationship, however, isn't exactly wholesome. Jealousy and a malevolent undercurrent intrude on their fantasy when Elisabeth invites the strange Agathe to stay with them -- and Paul is immediately attracted to her.
