Pushed by her meddling, snobbish mother, Mrs. Van Suydam, Evelyn Smith decides to end her stormy one-month marriage and divorce her husband Jack, a struggling lawyer. Seven years later, Jack and his legal partner, playboy Dave Talbot, are engaged by the Devonshires, a wealthy couple who are being sued by the working class Henry Populopulini. In hopes of settling the suit out of court, Jack invites Henry to meet with the Devonshires, whom Henry has accused of breaking up his son Anthony's marriage to their daughter Pamela, but during the confrontation, the stubborn Mrs. Devonshire becomes inflamed and leaves. Determined to mend matters, Jack calls Henry's lawyer for a meeting and is stunned when Evelyn walks through his door. Jack refuses to discuss Henry's case seriously, and Evelyn departs in a huff. Although Jack denies Dave's claim that he still loves Evelyn, he telephones her and, after apologizing, invites her to dinner. During the evening, Jack and Evelyn begin fighting over the case, which is subsequently sent to trial. A clever lawyer, Evelyn convinces the jury that Mrs. Devonshire was responsible for her daughter's annulment and wins a $100,000 verdict for Henry. Sure that Evelyn and Jack belong together, Judge Gorman, who presided at the trial, invites them for a round of bridge with Sam Walker and his wife. Gorman's hope of impressing Evelyn and Jack with the Walkers' "good" marriage explodes when the Walkers argue violently over a hand. Later that night, however, Jack, inspired by the Gormans' seemingly happy marriage, proposes to Evelyn, unaware that Mrs. Gorman has accused her husband of having an affair with Evelyn and is on her way to Reno. After Mr. Devonshire announces to Evelyn that he has defied his wife and, with Henry, has helped Anthony and Pamela to elope, Evelyn and Jack are invited to a spaghetti dinner at the Populopulinis'. During the dinner, the happy couple resorts to fighting again and drive into a raging rain storm, furious. After their car stalls in a ditch, Evelyn and Jack seek refuge at a farmhouse, where they pretend to be married. Following another verbal battle, the couple finally conclude that they must be in love after all.
