In September 1939, Władysław Szpilman (Adrien Brody), a Polish-Jewish pianist, is playing live on the radio in Warsaw when the station is bombed during Nazi Germany's invasion of Poland which caused the outbreak of World War II.

A mute Scotswoman named Ada McGrath is sold by her father into marriage to a New Zealand frontiersman named Alisdair Stewart, bringing her young daughter Flora with her. The voice that the audience hears in the opening narration is "not her speaking voice, but her mind's voice". Ada has not spoken a word since she was six years old and no one, including herself, knows why. She expresses herself through her piano playing and through sign language, for which her daughter has served as the interpreter. Flora later dramatically tells two women in New Zealand that her mother has not spoken since the death of her husband who died as a result of being struck by lightning. Ada cares little for the mundane world, occupying herself for hours every day with the piano. Flora, it is later learned, is the product of a relationship with a teacher with whom Ada believed she could communicate through her mind, but who "became frightened and stopped listening," and thus left her.

The story is told in medias res as a series of flashbacks. Max Tooney, a musician, enters a secondhand music shop just before closing time, broke and badly in need of money. He has only a Conn trumpet, which he sells for less than he had hoped. Clearly torn at parting from his prized possession, he asks to play it one last time. The shopkeeper agrees, and as the musician plays, the shopkeeper immediately recognizes the song from a broken record matrix he found inside a recently acquired secondhand piano. He asks who the piece is by, and Max tells him the story of 1900.
The Fabulous Baker Boys, Jack (Jeff Bridges) and Frank (Beau Bridges), are brothers living in Seattle, making a living playing in lounges and music bars, their gimmick being that they play intricate jazz and pop-flavored duets on matching grand pianos. Frank handles the business aspect while Jack, single, attractive, and more talented as a player, feels disillusioned and bored with the often hackneyed material they play. He is, nonetheless, able to live a comfortable and responsibility-free existence because of Frank's management, sleeping where and with whom he pleases. Frank has a wife and family he adores, but Jack has no personal connections in his private life, other than Eddie, his soulful but aging Black Labrador, and Nina, the lonely child of a single mom living in his building, who walks Eddie and takes piano lessons from Jack. In all other respects, professionally and personally, Jack's life is a series of empty one-night stands. Now and again, he plays the challenging music he really cares about at a local jazz club.

Intense young "tough" Thomas Seyr is a 28-year-old real estate broker involved in shady business deals. His business partners, Fabrice and Sami, spend much of their time ruthlessly chasing squatters and illegal immigrants out of the buildings they have procured and trying to work their way around government housing regulations. Thomas is born to this kind of work; his father, Robert, is also involved in dodgy enterprises and sometimes calls upon Thomas to beat up people who refuse to pay. Tom shows a protective and defensive attitude toward his father who doesn't always appreciate what his son does for him–so much so that when his father introduces his new girlfriend to Tom, Tom undermines her to her face, and insults her to his father, insisting she is an opportunistic "whore." Later, when he tries to enlist her help to watch over his father, she tells him they broke up due to Robert changing his attitude and she is aware of Tom's backstabbing because Robert told her. Robert by this time is in danger from a Russian gangster, Minskov (Anton Yakovlev) who scammed him out of 300,000 Euros and Tom is worried for his safety.
