Plot synopsis

Set in the fictional town of Thayer, Connecticut, the story focuses on Meredith Morton (Sarah Jessica Parker), a successful Manhattan executive whose uptight, conservative demeanor is a sharp contrast to that of her boyfriend Everett Stone's (Dermot Mulroney) liberal and rambunctious family. He has four siblings:

• Amy (Rachel McAdams) is a school teacher currently pursuing her Masters Degree and NPR supporter who has previously met Meredith and took an immediate disliking to her
• Thad (Tyrone Giordano) is a deaf and gay architect who lives in Boston and is contemplating adoption with his African-American partner Patrick (Brian J. White)
• Ben (Luke Wilson) is a stoner who makes documentary films and lives in Berkeley; he finds an immediate attraction to Meredith
• Susannah (Elizabeth Reaser), A housewife who has a young daughter, Elizabeth (Savannah Stehlin), and is expecting her second child.

The Stones' father, Kelly (Craig T. Nelson), is also an architect, and their mother, Sybil (Diane Keaton), a bohemian type who is dealing with the recurrence of a fatal illness, which isn't directly stated. It's implied that she had breast cancer previously, which has since metastasized (Metastasis).
