Maggie Conley has a miscarriage after an argument with her husband, Chris, turns physical. To save their marriage, they move to a large house in rural Virginia. They are met by a real estate agent, Rob Bradley, who explains that the house has been converted into a duplex. A quiet, elderly couple, the Andersons, rent the other half of the house. As constant storms have made public utilities prohibitively expensive, Bradley suggests that they use cell phones and a generator.
