Hermann works at NATO headquarters in Brussels and is only home on weekends. He is quite a male chauvinist. That is why his wife Merete has not told him that she has pursued a career in the army and become a lieutenant. In Merete's regiment, Senior Sergeant Vasby suspects her of being a spy because of her "mysterious" conversations with NATO. This develops into an amusing spy hunt, and many people get involved. When Hermann is called up again, he "forgets" to tell his wife.
