Eager to fit in with her upper-class peers, Kate Hartounian befriends the snobbish Mary Frances “Miffy” Young, who suggests that Kate and her father, Jack, become members of the Bushwood Country Club. Although Jack is a self-made millionaire who earned his money in real estate development, he remains humble and maintains a close relationship with his workers. While breaking ground on a low-income housing project in the community, he is threatened by the wife of the Bushwood Historical Society president, who strongly opposes Jack’s efforts to integrate the neighborhood. Unphased, Jack laughs at her and sends one of his workers to chase her off the property with a bulldozer. Despite his disdain for the club’s elitism, Kate convinces her father to meet with majority owner Ty Webb about applying for membership. At the club, Ty arranges for Jack to play golf with Miffy’s parents, Chandler and Cynthia Young, and Jack recognizes Cynthia as the woman he nearly bulldozed. As they tee off, Jack's abominable skills and boorish behavior amuse the Youngs’ friend, Elizabeth Pearce. Meanwhile, the Bushwood Historical Society pursues legal action to stop development on Jack’s housing project until he obtains permits from the city planning commission. Regardless, Kate begins a relationship with Miffy's brother, Todd Young, who oversees the Historical Society’s case against her father. At the club ball, Jack tangos seductively with Elizabeth, mortifying the onlooking guests. To escape the embarrassment, Kate sneaks outside and strikes up a conversation with a young caddy named Harry, who questions her obsession with joining upper class society. As she helps Harry with his golf swing, Todd appears and drags her away to another party. Back inside, Chandler officially rejects Jack’s membership application, but is unable to stop him from bidding on all the members who volunteered for the “society slaves” charity auction. To make a point about the value of earning an honest living, Jack puts them to work on his construction site. The disgraced club members retaliate by shutting down power at Jack’s office. Vowing to get even, Jack purchases Ty Webb’s majority shares and reopens the club as an amusement park. Frustrated by her father’s childish behavior, Kate moves into Miffy’s house. Meanwhile, Chandler hires retired U.S. Marine Corps Captain Tom Everett to go undercover and kill Jack, but the bumbling officer repeatedly misses his target. Giving him one last chance, Chandler instructs Everett to hide in the bushes with an explosive golf ball while he competes against Jack in a game that will determine the fate of the housing development. While Chandler plays with his son, Todd, Jack teams with Harry. Despite an early struggle, Jack and Harry move ahead and tie the score. Everett surveys the final hole from afar, but becomes distracted by Bushwood’s mischevious resident gopher, which shoots him in the buttocks with a poisoned dart. As the players prepare to make their putts, Kate retaliates against Miffy’s snobbery and apologizes to her father for disowning him. On the hillside, Everett begins to lose consciousness and misses his opportunity to hit Jack with the explosive ball. Once Jack successfully sinks his putt, the gopher replaces Chandler’s ball with the explosive ball, which detonates upon impact with the club. Chandler is badly burned, and Jack wins the game. Kate kisses Harry, while Jack and Elizabeth embrace in celebration of their victory.
