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.
In June 1990, five teenagers fail to complete a crawl of 12 local pubs in Newton Haven. Two decades later, the ringleader of that motley crew, Gary King, reunites the lads to complete the booze-fuelled feat.
