Tracy Lord (Katharine Hepburn) is a wealthy Main Line Philadelphia socialite who divorced C.K. Dexter Haven (Cary Grant), a member of her social set, because he did not measure up to her exacting standards. (He was an alcoholic, and her lack of faith in him exacerbated his condition.) She is about to marry nouveau riche "man of the people" George Kittredge (John Howard); the wedding and its preparations form the backdrop for much of the movie.Spy magazine publisher Sidney Kidd (Henry Daniell) is eager to cover the wedding, and he enlists Dexter, his former employee, to introduce reporter Macaulay "Mike" Connor (James Stewart) and photographer Liz Imbrie (Ruth Hussey) as friends of the family so they can report on the wedding. Tracy is not fooled but reluctantly agrees to let them stay--after Dexter explains that Kidd has an innuendo-laden article about Tracy's father, Seth (John Halliday), who, Tracy believes, is having an affair with a dancer. Though Seth is separated from Tracy's mother Margaret (Mary Nash) and Tracy harbors great resentment against him, she wants to protect her family's reputation.Dexter is welcomed back with open arms by Margaret and Dinah (Virginia Weidler), Tracy's teenage sister--much to Tracy's annoyance. In addition, Tracy gradually discovers that Mike has admirable qualities. Thus, as the wedding nears, Tracy finds herself torn between her fiancé, her ex-husband, and the reporter.The night before the wedding, Tracy gets drunk for only the second time in her life and takes an innocent swim with Mike. When George sees Mike carrying an intoxicated Tracy into the house afterward, he thinks the worst. The next day, he tells her that he was shocked and feels entitled to an explanation before going ahead with the wedding. Tracy takes exception to his lack of faith in her and breaks off the engagement. Then she realizes that all the guests have arrived and are waiting for the ceremony to begin. Mike volunteers to marry her (much to Liz's distress), but Tracy graciously declines. At this point, Dexter makes his bid for her hand, which she accepts.(From Wikipedia)
