 Police Constable Nick Rowan moves from London to Aidensfield, North Riding, Yorkshire to be the new village bobby with his wife Kate, who was born and grew up in the area and hopes for a position with the local GP Dr. Ferrenby. Rowan soon starts to make himself known among the locals and gets his first case. A woman thinks she is being stalked and wants him to look into it. Furthermore there is trouble brewing between local boys on motorbikes and outside hooligans for him to deal with, and his new section sergeant, the old-fashioned Oscar Blaketon from the nearby Ashfordly police station whose lifelong ambition it is to see the local rascal Claude Jeremiah Greengrass behind bars, is giving him a hard time too.
