Original title: Mijn nachten met Susan, Olga, Albert, Julie, Piet & Sandra

Susan has chosen a hermit's life on a dilapidated farm over the shallowness of her previous jet set modeling life. When Anton, a hunky courier, comes along to pick her up for an assignment on the French Riviera, he's so fascinated by Susan's odd assortment of house guests that he decides to stay with them for a couple of days.
