One thing gives them the promise of a better future—Radio Hope, a mysterious station that broadcasts vital information about surviving in a blighted world. But when a mad prophet and his army of fanatics march out of the wildlands on a crusade to purify the land with blood and fire, all three will find their lives intertwining, and changing forever.
