A world gone mad: Four weeks after a plague has swept the world - a virus that unlocks the genetic insanities that lurk in all of us.
The epidemic affected everyone, the entire human race gone insane. Now the incapable mad - the catatonic, depressed, schizophrenic - are dead. The only ones left are the functional insane. Megalomaniacs, psychotics, those whose insanities are adaptive in this new world, roam the land, preying on the weak.
A small band of survivors who believe themselves still sane fight for survival and the chance to build a better life. But are they really sane, or are they just deluding themselves?
