Anytown, England. Jeremy Shepherd has reached post-ambition, giving up the trappings of his London life (flash job, flash cars, even flashier girlfriends) to move back to his home town and his parents' house. By day, he is a low-level civil servant, chained to his desk and content to idle away the hours filing and answering emails. There isn't a lot to do in a small town, but the English are very resourceful and Jeremy quickly finds a hobby that delivers lots of fresh air and exercise. By night, he prowls local car parks to indulge in altogether more challenging pursuits – anonymous sex with strangers. This is no ordinary hobby – each encounter is tinged with a definite air of danger, as police stake out each site and the cloak of anonymity brings its own risks.
As the scene's night-time liaisons increasingly threaten the sensibilities of the local Daily Mail readers, things take a turn for the worse. Locals take a dislike to the illicit rendezvous and as the police step up surveillance, private pursuits risk becoming very public.
