The world has been left in ruins following the outbreak of a terrifying disease. Deep in the Australian countryside, a group of survivors are locked in a constant struggle to stay alive. After a savage battle against a rival group, their leader and the majority of their village begin a search for safer habitation, leaving only a few behind to defend their home, from 'Marauders,' and the dreaded, 'Infected.' But when they capture a female Marauder, the group is shaken to the core, and forced to confront an even greater enemy. Each other.
