The supernatural trinity has been broken.

There is little left of Hal's humanity. Having feasted on blood and recruited an army of vampires, he's ready to return to his hedonistic and debauched days. Tom is set on revenge and has returned to his default setting – vampire killer, with one vampire in mind. Alex is trapped in a hellish prison by Captain Hatch.

Unbeknown to them all, Hatch is no longer wheelchair-bound and weak; he's regained his strength and is determined to cause as much chaos, death, and destruction as possible.

Hal, Tom, and Alex do battle with the Devil in order to save the world - but at what price to their own humanity?

After his death four years ago, his friends and family thought they'd never see Kieren again. But then, shortly after his funeral, thousands of the dead were reanimated, and after months of rehabilitation and medication the zombies - now known as PDS (Partially Deceased Syndrome) sufferers - are gradually being returned to their homes.

Since the passing of the PDS Protection Act, the government has set an agenda of acceptance and tolerance, but that agenda is at odds with the communities abandoned at the time of the rising and the bloody battle between zombies and humans that ensued.

Kieren returns to his home in the rural village of Roarton - a cauldron of brutal anti-zombie sentiment and the source of the "rotter"-hating Human Volunteer Force (HVF) - where he is forced to confront his family, the community that rejected him, and the flashbacks that continue to haunt him of what he did in his untreated state.

His parents, Steve and Sue, are undoubtedly pleased to see him but his sister, Jem, isn't so ready to pick up from where they left off.

Meanwhile, the HVF, led by violent Bill Macy and backed by local churchman Vicar Oddie, are ready to take action against any PDS sufferer reintegrated on their patch.
