Led by a discredited soldier named John Hammond, the small caravan of survivors learns that they have no choice but to unite or die. Earth, the New Frontier is a story of everyday people under adverse conditions. With death never more than a step behind them, the characters face insurmountable challenges as they struggle for their very existence.
