In a post-apocalyptic world where a biotech virus has transformed humans into violently deranged cannibals, a bereaved mother who has lost everything shelters in an isolated mountain cabin while teetering on the edge of giving up. When a desperate stranger arrives with a story of hope, she must choose whether to help or remain hidden. With time running out and the oppressive totalitarian G. M. A organization closing in, her only escape is through the infested forest where danger lurks in every shadow.
