Les amours de Paris focuses on three disparate couples and their problems in the arena of romantic love. One couple is comprised of a faithful husband and a sick wife whose stay in the hospital is not so bad because she has taken a sudden interest in her doctor. In the second pairing, a womanizer comes to see that the model who is in love with him is worth more than yet another conquest. And to complete the trio, two zany people finally realize they are a couple.
