THE FAMILY STONE is a comic story about the annual holiday gathering of a New England family, the Stones. The eldest son brings his girlfriend home to meet his parents, brothers and sisters. The bohemian Stones greet their visitor – a high-powered, controlling New Yorker – with a mix of awkwardness, confusion and hostility. Before the holiday is over, relationships will unravel while new ones are formed, secrets will be revealed, and the family Stone will come together through its extraordinary capacity for love.
Sybil Stone (DIANE KEATON) is the strong-willed matriarch who is at the heart of the Stone family, an outspoken woman who wants only the best for her five children. Strikingly beautiful, her face now reflects a recent note of brittleness or fatigue, suggesting that perhaps Sybil carries a secret.
