Christmas 1893, New York City — Hannah Bell drags her son Donny on a sled through the snow to a children’s clinic, where she presents a false name to avoid paying. She reads in the paper that John Burton has been named vice president of the Knickerbocker Bank. Furious, she seeks out her father’s old friend, bank president Asa Cabot, and demands that she withdraw all of her substantial assets immediately. Cabot refuses Burton’s resignation and instead escorts Hannah to the vaults, setting the stage for a lifelong struggle over wealth, control, and love.
Kate Farley visits the clinic (a generous supporter of the facility) and recognizes Donny. They reconnect, and Kate visits Hannah again, urging her to donate $500 to the clinic under her real name.
In 1904, on her way to her current bank, Hannah uses a clever ruse to have a conductor pay for her ticket. She clips coupons in her own vault—her assets now rival the bank’s—and she flatly states that she is saving everything for her son. A client recognizes her as the “tightest tightwad” in New York.
Donny has grown into a brilliant student and becomes the valedictorian of his Princeton University class. He dreams of writing, but Hannah pushes him toward the bank and its steady letters, shaping his path in contrast to his artistic aspirations.
In 1906, Kate invites Dr. Lorimer to Newport to assess Hannah, and he nicknames her “Hannibal.” Lorimer notes that her mental state has deteriorated over thirty years, tracing it back to her marriage to a fortune-hunter, Harry Bell, who died leaving her to raise Donny in poverty. Her relationship with John Burton had been called off at the last minute when he sailed for Europe. Lorimer suggests bringing Hannah and Burton together—not to reconcile them, but to uncover what scarred her so deeply.
Cut to Kate struggling to give Hannah a fresh hairdo, a new evening dress, and silk stockings. Hannah is secretly pleased, though Burton cannot attend the party. The next day, Lorimer introduces Donny to Burton’s daughter, Elizabeth 'Beth' Burton Bell.
Hannah grows furious when she learns that Donny has met Burton, exposing Kate’s plan, but the young couple continues to see each other. Nearly a year later, Donny proposes, and Elizabeth fears that he cannot stand up to his domineering mother.
Hannah storms into Burton’s office and accuses him of trying to gain control of her money through Elizabeth. He refuses to interfere with the couple, though he suspects that Donny has inherited his mother’s father’s “taint”—pathological avarice.
Cut to the bridal party exiting the church, flanked by friends. Hannah watches from behind a tree, a witness to both joy and strife.
The Panic of 1907 hits. The Clearing House Committee asks Hannah for a critical loan backed by gilt-edged securities. When she sees a $5 million demand loan backed by Burton’s own railroad shares, used to pay depositors, she agrees to provide the loan. Burton forfeits his stock rather than abandon his depositors.
Donny and Elizabeth return from their European honeymoon to headlines that Hannah has wrested control of the railroad from Burton. At the bank, Donny confronts Hannah in the vault, telling her she has never loved anything—including him. He also reveals he does not blame Burton for walking away after she and her father tried to force him to sign an agreement never to touch her money. He shows her the paper Burton kept, and she accepts that he believes she knew better. Hannah then follows him into the street, where she discards a pocketful of money as a crowd swarms around them.
Cut to Hannah sitting on a park bench in a cold winter night, after the public drama has cooled.
Donny and Elizabeth prepare to move on; he takes a position at a San Francisco newspaper, revived after the 1906 earthquake, while Kate encourages them to visit Hannah. He declines for now.
Back at Kate’s house, Hannah faces a fourth week of pneumonia. Donny arrives, and they share a tearful embrace and forgiveness. Burton enters, thanking her for returning the railroad stocks, which she dismisses. Dr. Lorimer observes that she has had enough excitement for one day, and Hannah fires back with a final quip, > Say, whose pneumonia is this, yours or mine?
