Everett Stone, who made it on Wall Street, returns home for Christmas with his new girlfriend, Meredith Morton. His ultra-liberal, anti-conventional rustic Connecticut family doesn't exactly warm to the outsider, who despite her best efforts to please the prospective in-laws, looks, sounds, and acts like the conservative bigots they hate, while various Stones have their own problems. Only matriarch Sibyl Stone's unshakable maverick other son Ben gives her a chance, and as Everett won't actively turn against either, she feels more supported by him and a weird romance blossoms. Feeling beleaguered, Meredith calls in help from her easygoing sister Julie, who proves no help to her but soon develops a chemistry with Everett, so everything may now shift if they dare follow their hearts.
