Georgie Soloway (Dustin Hoffman) is an unbelievably successful composer of popular music. Just in the last year, he has written over 60 hit songs. That kind of output worries him, however. Now that he is getting to be middle-aged, he wonders if he will be able to keep the pace he has set. He also has a rich crop of neuroses, and his worries go way beyond what might seem reasonable. For instance, Georgie believes that someone named Harry Kellerman sabotaged each of his previous relationships, and he is worried about his current one with Alison (Barbara Harris), a singer. He seeks the aid of his psychiatrist (Jack Warden) but gets little satisfaction. He then tries to get comfort from his business associates (Dom De Luise and Gabriel Dell), but they don't have a clue about how to help him. Turning to home, he visits his mother (Betty Walker) and father (David Burns) but is further distressed when he learns that his father is dying. Still highly agitated, he takes to the air in his private jet.
