Shaun is fast approaching his 30th birthday and can't escape the nagging thought that life is passing him by. Just when it seems all hope is lost, Shaun is given a chance to prove his worth when a zombie holocaust sweeps across London, transforming all of Shaun's neighbours into the walking undead. He gathers together the people he loves then heads to the local pub, The Winchester, which has always been his refuge in times of need.
Police Constable Nicholas Angel is one of the Metropolitan Police's shining lights - he's so good at his job, in fact, that he makes all of the other officers look bad in comparison. So Nicholas's superiors transfer him to the sleepy West Country backwater of Sandford, where nothing ever happens. Assisted by clumsy local constable Danny Butterman, Nicholas discovers that his new home isn't as idyllic as it appears, and that beneath the surface, Sandford harbours at least one psychopath with an insatiable bloodlust.
