September and dreary weather on the North Sea coast. Tomke Heinrich ends up in bed with Karl, her summer acquaintance. A fiasco. Tomke flees to her guesthouse, but the day has another surprise in store for her: Tomke's childhood friend Dörte is at the door and needs help. And then there's Dagmar, Dörte's youthful, life-hungry mother, who sets off a carousel of misunderstandings, deception, a lot of money, and love through a harmless act of friendship.
