Fred Benson, in the insurance business in Omaha, is married to a dreary woman who gives him oatmeal every morning and liver every night until he begins to dream about her in her coffin. Via his computer he determines the likeliest way for her to die and with the help of some bath oil and a telephone call she slips in the bathtub. From then on he doesn't have a free minute in between his sexually consuming secretary and a widow (whose husband he had disposed of) and it isn't long before they collaborate and assist him toward a more living end.
