Mia (Trine Dyrholm) is happily married to likeable high-school headmaster Frederik (Nikolaj Lie Kaas). When it turns out that Frederik has embezzled school money, Mia faces a crucial dilemma.

This mosaic of seemingly unrelated fragments is a study of the human mind, which might be more complicated than we thought.
