A new sergeant arrives at Aidensfield police station, bringing plenty of radical ideas from his time in the city, much to the officers' disgust. When news gets out of his ambitious plans, which will leave Walker unemployed, Oscar decides to take a stand and rallies the troops.

PC Walker receives a tempting offer from an old friend, but as the proposition involves a spot of rule-bending on his part, the decision to go through with it could land him in serious trouble, especially as Sergeant Miller already seems less than impressed by the policeman's rebellious nature.

Bellamy tries to impress Miller by going it alone, while the arrival of tax inspector Derek Ford gets the residents of Aidensfield panicked. Vernon bears the brunt of Ford's wrath when his dodgy dealings and poor record-keeping are exposed, convincing the wheeler dealer the only way to avoid trouble is to fake his own suicide.

Clare finds herself under suspicion when a wild party ends in tragedy with a drugs-related death, and Miller is annoyed to have to reprimand Walker once again when he discovers his participation in the drunken revelling. David is put in a tricky situation when his Aunt Peggy arrives in Aidensfield and sets up an illegal vodka still, while Ventress is quick to reveal the newcomer's dubious history to Oscar and Gina.

A crime wave hits Ashfordly train station as a number of freight wagons mysteriously vanish, giving the police a tricky case to crack, but a sandwich could provide a vital clue. Peggy has plans to make some fast money when she decides to play dirty in the local bowls tournament, while a night out in Whitby proves eventful for Walker and Helen.

A young girl is injured in a horse riding accident, leading the police to stumble upon a sinister series of animal thefts. Helen tries to tell Rob she doesn't want a relationship with him, but worries about hurting his feelings. Meanwhile, Oscar catches Peggy and David hosting a poker tournament in the Aidensfield Arms and bars them from the pub.

A young boy is shot at the Hall and Lord Ashfordly comes under investigation for employing child labour - but Bellamy discovers that the truth is rather more complicated. Peggy turns her hand to the tourist industry.

Peggy sets aside her pitchfork for glamour in the hope of charming a wealthy widower. The local community is up in arms when a famous homicide case is reopened for investigation - but Sergeant Miller ends up with more murder than he bargained for.

A group of young offenders come to stay at Ashfordly Hall, but soon find themselves under suspicion after a spate of disturbances in the village. Meanwhile, Blaketon and Ventress go on the hunt for a spinster's missing dog, and a £50 reward gives Peggy an idea.

A witness of a hit and run is sure it was no accident and Peggy acquires some cheap cigarettes which are not what they seem.

Gina discovers a severed hand in her dustbin.
