Arthur Bach is a spoiled, alcoholic man-child in
New York City, who likes to be driven in his chauffeured
Rolls-Royce Silver Wraith limousine through
Central Park. Arthur is heir to a portion of his family's vast fortune, but only if he marries the
upper-class Susan Johnson, the daughter of Burt, a business acquaintance of his father Stanford. He does not love Susan, but his family feels that she will make him finally grow up. During a shopping trip in
Manhattan, accompanied by his valet, Hobson, Arthur witnesses a young woman, Linda Marolla,
shoplifting a necktie. He intercedes with the store security guard on her behalf, and later asks her for a date. Despite his attraction to Linda, Arthur remains pressured by his family to marry Susan. While visiting his grandmother, Martha, Arthur shares his feelings for Linda, but is warned again that he will be
disowned if he does not marry Susan. Hobson, who has been more like a father to him than Stanford has, realizes that Arthur is beginning to grow up, and secretly encourages Linda to attend Arthur's engagement party. Hobson confides in Linda that he senses Arthur loves her. Linda crashes the party, held at Stanford's estate, and she and Arthur eventually spend time alone together, which is tracked by both families. Hobson is later hospitalized, and Arthur rushes to his side, vowing to care for the person who has long cared for him. After several weeks, Hobson dies, and then Arthur, who has been sober the entire time, goes on a
drinking binge. On his wedding day, he visits the
diner where Linda works and proposes to her. At the church, he jilts Susan, resulting in Burt Johnson attempting to stab Arthur with a
cheese knife, though he is prevented by Martha. A wounded Arthur announces in church there will be no wedding, then passes out soon after. Later, Linda tends to his wounds, and they discuss living a life of poverty. A horrified Martha tells Arthur that he can have his fortune, because no Bach has ever been
working class. Arthur declines, but at the last minute, he talks privately to Martha. When he returns to Linda's side, he tells her that he declined again – Martha's dinner invitation, he means – but he did accept $750 million. Arthur's pleased
chauffeur Bitterman drives the couple through Central Park. == Cast ==
