It is 2029. The Mandibles have been counting on a sizable fortune filtering down when their 97-year-old patriarch dies. Yet America's soaring national debt has grown so enormous that it can never be repaid. Under siege from an upstart international currency, the dollar is in meltdown. A bloodless world war will wipe out the savings of millions of American families. Their inheritance turned to ash, each family member must contend with disappointment, but also, as the effects of the downturn start to hit, the challenge of sheer survival. Recently affluent Avery is petulant that she can't buy olive oil, while her sister Florence is forced to absorb strays into her increasingly cramped household. As their father Carter fumes at having to care for his demented stepmother now that a nursing home is too expensive, his sister Nollie, an expat author, returns from abroad at 73 to a country that's unrecognizable. Perhaps only Florence's oddball teenage son Willing, an economics autodidact, can save this formerly august American family from the streets.
