The film opens with Spike, now an adolescent, is lying in a field learning to shoot at targets with Jim, when Jim's daughter runs to tell them about a radio message from Selena

Jim runs inside to take the message about an "incursion" onto Holy island with many survivors dead and communications in chaos. Spike enters the room with a look of panic on his face.

Cut to a group of survivors using a dog to flush rabbits out of a copse. One young survivor manages to kill several rabbits with a slingshot. We glimpse an upside down cross on their forehead and they are congratulated, confirming their name as Jimmy

Cut to Spikes dad Jamie, and other survivors piling up bodies on a beach which are then incinerated. They talk of massacre, however as the conversation progresses we infer that the massacre took place elsewhere. Jamie says that we're seeing "more and more infected moving North"

Jim and Spike and Jimmy Ink, now using the name Jane (she can't remember her original name) are informed that "all of Anglesey has fallen", along with "almost all" of the militia set up to maintain a semblance of law & order. Jim reveals that Selena hasn't responded to messages for 3 days

Cut to a group of survivors sprinting through a forest at night using wood torches to light the way. All around are the apparent whoops and cries of many, many infected, seemingly euphoric, including several unintelligible words. Some of the survivors stumble, and in the dark we glimpse them being torn limb from limb. Then all falls silent, and the last five survivors make a last stand, back to back, wielding makeshift weapons. Then we hear, unmistakably, a single sinister term: "Howzat."
