Synopsis:

The uneasy existence of upper middle-class suburbanites Agnes and Tobias and their permanent houseguest, Agnes' witty alcoholic sister Claire, is disrupted by the sudden appearance of lifelong family friends Harry and Edna, fellow empty nesters with free-floating anxiety, who ask to stay with them to escape an unnamed terror. They soon are followed by Agnes and Tobias's bitter 36-year-old daughter Julia, who returns home following the collapse of her fourth marriage.
