In their finely appointed Connecticut home, Agnes and Tobias have grown used to the imperfection and fragility of their marriage. Quietly nursing their grief over the death of their son, they get by well enough together. Agnes' boozy sister wanders in and out, and they allow anxiety-stricken friends to move into an upstairs room. But, when their daughter, Julia, shows up announcing her fourth divorce, long-repressed emotions come to the surface.
