The family are hiding a downed British pilot, the blonde guy, Durand, is a collaborator who's trying to ingratiate himself with the Germans by reporting the kid for singing a British song he learned but even the Germans think he's a fucking tryhard. He gets executed by the resistance at the end. Not on screen, but you see him being dragged off and you hear the shot. It's a good show, everyone is portrayed as very human and it's not being French or German that makes people shitty, it's their own failings.
