The planet has gone to hell. A mysterious pathogen is killing billions with just as many being left dangerously damaged, physically and psychologically.
As these hordes run wild in Australia's cities and countryside, small pockets of humans, who remain untouched by the disease, hide away in reinforced bunkers. They scathingly refer to those who attack them as Ga-Gas.
In one such isolated beachside hideout, six mismatched humans — four men and two women — struggle to put order back in their lives. They must deal with their own losses and failings and come to terms with a harsh new reality of kill or be killed.
Then they discover their dictatorial leader's daughter — a former national TV star — is being held as human trophy by a mad Ga-Ga leader and his army of rabid followers.
The story's often sceptical narrator, who once loved but then lost the now captive woman, sets out with her rage-fuelled father and a roguish car thief to rescue her. What could possibly go wrong for this quarrelsome trio? Plenty.
