The film follows Mabel, a woman who is bit little mad. She is married to Nick, who is a construction worker of some kind. They have three kids together but little privacy - they sleep on a pull-out bed in the dining room. When Nick and Mabel are alone, they seem really tender, but they often both fighting with each other and other people. Mabel is deemed insane by people in the film - and maybe she is, a little. She talks too fast and too much. She makes others uncomfortable by invading their personal space. She drinks too much, too fast. Later in the film she does seem to suffer from total breakdown, and Nick has her hospitalized. Of course, that's not the end of the film. While Mabel is gone, we see how insane Nick is (forcing the kids to "play" on the beach and then sharing his six-pack of beer with them). Sometimes, as Ebert mentions, two sort of crazy people sort of fit well together.
