The unconventional Stone family gather to meet Meredith (Sarah Jessica Parker), the woman who their eldest son plans to propose to. The family give Meredith a hostile reception and she calls on her sister Julie (Claire Danes) to join her for moral support. Unfortunately for Meredith, the Stones take an instant shine to Julie, and further complications quickly develop.
