Love is war, and sex is the battleground in this wry, funny look at contemporary mating and relating. Kate (Famke Janssen) is a magazine writer who discards boyfriends the way some people change shoes. Adam (Jon Favreau) is a serious-minded serial monogamist. When they meet, it's love at first sight -- but staying together may take more than just love and a liberal dose of sex. Noah Emmerich and Cheri Oteri co-star.
