Howard has a loving wife (Garner), two daughters, a prestigious job as a Manhattan lawyer, and a comfortable home in the suburbs. But inwardly he's suffocating, and eventually he snaps and goes into hiding in his garage attic leaving his family to wonder what happened to him. He observes them from his window - an outsider spying in on his own life - as the days of exile stretch into months. Is it possible to go back to the way things were?
