The collapse of civilization has left the survivors scattered among a few settlements along the wilderness fringe of a land ravaged by war. Preyed upon by roving bands of sadistic ex-soldiers and ever at the mercy of a natural world that has turned against them, a family is facing their final days. Hope appears in the guise of their young son--raised in isolation and taught by his father to survive at any cost, he helps rescue a group of captives from a savage and relentless cult and is thrust headlong into a battle for his future and the future of humankind.
