In the film, Nicholson plays David Staebler, a melancholy Philadelphia disk jockey who tells long, angst ridden stories of his childhood over the radio and lives with his elderly Grandfather (Lavine). David receives a call from his extroverted con artist brother Jason (Dern) asking him to bail him out of jail in Atlantic City. When David arrives he gets caught up in Jason's scheme to develop a South Pacific island into a gambling casino so that the brothers can "fulfill their childhood dream of an island kingdom of their own".
