 When former Wall Street executive Peter Salem is released from prison, he heads for the small town of Bunker Hill, Kansas, where his ex-wife and their children have started a new life. Soon after he arrives in town, all power is lost - there is no electricity, and cars and computers suddenly shut down. Community leaders are at a loss to explain. Is it the rapture? A massive terrorist attack? Aliens? Cut off from the world, the town s militant past is reawakened and forces coalesce to protect citizens from an unseen enemy, represented to some by Mr. Farook, an elderly Pakistani immigrant who owns the local convenience store. The town s fear leads to the creation of a posse of gunmen, resulting in torture, illegal searches and eventually, murder.
