American horror in which a man and woman have their survival skills tested when a deadly virus wipes out most of civilisation. As Teresa (Kate Flanagan) and Matthew (Michael Izquierdo) wander the landscape in search of safety and shelter from the virus, at all times they must avoid being attacked by live infected victims but soon discover the virus is prevalent everywhere. When Matthew contracts the virus and becomes ill, the only way to defeat it is to be injected with an antidote which induces madness. Time is running out for Matthew, and Teresa must decide whether to stay and help him or to flee and fight for her own survival alone.
