After mushroom clouds appear on the horizon, fear of the unknown propels Jericho into social, psychological and physical mayhem when all communication and power is shut down.

What happens to a group of people when disaster strikes? Do they rally together or fight for their own survival? These are the questions explored in Jericho after a mushroom cloud appears on the horizon of the small Kansas town, knocking out electricity and communications.

A mix between Lost and Lord of the Flies, Jericho reveals the social dynamics that emerge within a group that's cut off from the outside world and forced to rely on one another. While some people fight over hoarded gasoline, others help their neighbors in unexpected ways.
