We first see the adult David Helfgott (Geoffrey Rush) as a rumpled schizophrenic, living semi-assisted in a boardinghouse in modern Australia, compulsively mumbling in stream-of-consciousness fashion. Flashbacks show he's the music-prodigy son Peter Helfgott (Armin Mueller-Stahl), a Polish Jew who lost his family in the Holocaust, left coldly possessive and distrustful regarding his star son. Peter can be a nice dad to his other, less talented children, but to young David (Noah Taylor) he's a demanding tyrant, driving the boy to win high-profile piano competitions and master a notoriously difficult Rachmaninoff concerto. David disobeys his father to accept a music scholarship in faraway London, getting himself forever banished from the Helfgott household. Even away from his father David's social isolation and instability worsens, and he suffers a mental breakdown. Returning to Australia, David is in and out of mental institutions, but when he proves his virtuoso piano-playing prowess in a bar one night he gets a gig as a saloon entertainer. Marrying a warm-hearted astrologer (Lynn Redgrave), David ultimately returns to the concert stage.
