Physics professor Sophie and divorce lawyer Stefan have been living together as a couple for 15 years. Sophie would like to get married, but because of Stefan's experience with his clients, he doesn't believe in long, happy marriages. The two make a bet: If Sophie shows him a truly happy couple that has been married for more than five years, he will marry her.
