On a typical autumn afternoon, Martha hosts a group of middle-aged women at her suburban home. The day takes a sudden turn when Elisabeth, an estranged friend, turns up unexpectedly - and she isn't the only unwanted guest at the tea party. Martha's sister, Maureen, shows up after years of radio silence, along some painful memories and a lot of confusion. Martha disappears after a simple trip to the backyard for herbs. Martha is the most beloved of the women, but will any of the others be able to look past their own problems long enough to search for her?
