It is a warm summer evening in North Zealand. Black clouds pull up over the horizon and threaten thunder. Margit (Berthe Qvistgaard) is on a bicycle from the small boarding house, where she has settled down during her summer vacation - on her way to a party with a friend who lives a few kilometers away. Margit is in a black style dress and looks pretty amazing, but it is necessary. The hostess has decreed that all her guests should all be in black: "It looks so swell on my white terrace".
