Margie and Ellie are two elderly sisters from North Dakota. Recently widowed and abandoned by their husbands and left penniless, the two sisters decide to operate a sex chat line from their farm, all the while trying to hide the true nature of their 900 business from their respectable neighbors of Himmel. When Ellie's husband Stanley turns up dead in the barn, Margie and the townsfolk go to extraordinary lengths to hide the true nature of his death from Ellie—which ultimately turns out to be murder.
