Somewhere in L.A., Peter (Kenneth Branagh), a washed-up British playwright, struggles to duplicate his past glory as he surfs a foul-smelling tide of disenchantment. His wife, Melanie (Robin Wright Penn), manages to maintain an optimistic outlook even as she longs for the baby that her husband is hesitant to help her conceive. When Peter befriends Amy (Suzi Hofrichter), a neighborhood girl who has mild cerebral palsy, their friendship softens him to the idea of fatherhood and propels Melanie's maternal yearnings into hyperdrive. As if baby fever weren't enough, Peter is plagued by a seemingly benevolent stalker (Jared Harris), his neighbors' incessantly noisy dog, and the flighty cast and crew of his latest play.
