Michelle is in her early 30s. Linda is in her late 40s. Michelle is an interior designer and newlywed to Robert. Linda lives alone; she fills her days with painting and exercise classes. Seeking a new friend, Linda pursues Michelle after one of their classes together, insisting the young designer come over to assess Linda's self-described dump. Played out as an attempt to cheer Michelle up about her doubts on marriage, Linda, rippling with an undercurrent of startling jealousy and delusion, begins an intricate game of cat and mouse between herself and the younger woman - a woman she doesn't intend to let go of anytime soon.
