Margot's (Margit Carstensen) and Kurt's (Ulrich Faulhaber) marriage happens smoothly and without much ado but also without great emotion—an inconspicuous relationship of the type one tends to call harmonic. Margot and Kurt live in Kurt's mother’s (Brigitte Mira) house, where his sister (Irm Hermann) and her husband (Armin Meier) live as well. This is a source of friction, sometimes even open conflicts, especially when the mother forcefully intrudes into Margot’s life. Since funds will be limited until Kurt finishes evening classes, these conditions are accepted, even by Margot: One must try to fit in and one must learn to subordinate oneself if circumstance so demands, even for the sake of losing your mind. A claustrophobic, intense psychological study of a housewife that breaks under pressure and slowly drifts into insanity.
