Merton and Jenny's honeymoon is cut short when Jenny's health takes a turn for the worse, and Merton receives another blow when he returns to Ashfordly station to find Ventress has let standards slip in his absence, which has incurred the wraith of a constabulary inspector whose car has been stolen. With the reputation of the station at stake and a flash car to find, the team have a lot on their plate when a crooked travel agent cashes in on local holiday-makers absence. Meanwhile, Vernon's fortune comes crashing down when he makes a disastrous investment whilst organising a Bentley rally at Ashfordly Hall, whilst Gina isn't happy at the thought of giving up the Aidensfield Arms to marry a policeman.

Blaketon asks Steve to accompany a group of delinquents on an outdoor adventure course on the moors, but trouble is not far behind when two cousins manipulate their way onto the trip with an ulterior motive. Meanwhile, Vernon's latest venture sees him unsuccessfully trying to persuade Lord Ashfordly to rent out Ashfordly Hall to a religious sect looking for somewhere to hold their meditation convention. Elsewhere, Steve's mother Babs returns to Aidensfield and makes it clear she is back for good by getting a job as assistant librarian to Joyce Jowett.
