Ben Jordan (Bruce Willis) and his wife Katie (Michelle Pfeiffer) have been married for fifteen years; they have two children, Erin (Colleen Rennison) and Josh (Jake Sandvig), a nice home and a comfortable life. Their happy marriage, however, turns into a sham—a performance they deliver daily for the benefit of their children, while behind the scenes they cannot stand each other anymore. Sending their kids off to summer camp, Ben and Katie commence a trial separation, during which both try to recall what it is about the other that led them to fall in love in the first place.
