Nicholas Angel (Simon Pegg) is the finest police officer London has to offer, with an arrest record 400% higher than any officer on the force. He's so good, he makes everyone else look bad. As a result, Angel's superiors send him to a place where his talents won't be quite so embarrassing -- the sleepy and seemingly crime-free village of Sandford.

With garden fêtes and neighborhood watch meetings replacing the action of the city, Angel struggles to adapt to his situation and finds himself partnered with Danny Butterman (Nick Frost), an oafish but well meaning young Constable. Just as all seems lost, a series of grisly accidents motivates Angel into action. Convinced of foul play, Angel realizes that Sandford may not be as idyllic as it seems. With his faithful partner in tow, Angel fights to prove his instincts are correct and uncover the truth about Sandford. Is Angel simply losing his mind in the safest, sweetest village in Britain? Or is something far more sinister at work? A small village is about to get some big city justice.
