In 2069 A.D. a divided nation and the world are recovering from a devastating climate change event. A cabal of wealthy families controls the Eastern industrial states. The Midwest has been ravaged by cycles of flood and drought, leaving many to rely on Christian charities.

When a charismatic preacher declares the imminent second coming of Christ will occur in California, a caravan of 100,000 desperate Christians is determined to defeat the border wall and enter their promised land. Their fate hangs on the actions of a small band of young operatives whose lives will be shaped by politics, romance and the operatives of the state who pursue them.
