It is about the Commandant of Auschwitz who was in charge as a million Jews were murdered.
The film watches the quotidian routines of the Höss family, whose house and extensive garden is right outside the camp. It is filmed with hidden cameras and follows the family through their lives, escaping from the constant rumble, screams, dogs barking, gunshots and other noises of the camp which is just beyond the wall. This is where the sound design and other visuals come into their own.
The acting is understated and there are some small references to the horror just the other side of the barbed wire, or down the river which runs close to their house and garden.
