Marilyn Jordan is a bored, depressed American housewife, married to a rich Swedish businessman with two seemingly perfect children. She tries to "spice up" her existence by surprising the family when she eats their entire dinner, setting the bedclothes on fire and poisoning the pet dog's milk and then advising it not to drink (the dog does not drink). Eventually Martin, Marilyn's husband, decides to have a psychiatrist see her, but it only serves to provoke her behaviour, and further exacerbate her frustration.
