Gina makes a surprise return to Aidensfield and Bellamy's delight sees him take his eye off the ball when he encounters a key informant who proves to be quite useful, causing catastrophic consequences for his career when the informant disappears before he can give the police a tip-off about an imminent armed robbery performed by a highly-dangerous London gang. Meanwhile, Lord Ashfordly hires a new land manager called Ben Morton, who faces opposition from protesting villagers when he makes plans to tear down the cottages tied to the estate. Liz joins the protest alongside Jenny, causing sparks to fly between her and the newcomer, whilst Vernon buys a miniature railway from Lord Elisby's bankrupt estate in his latest scheme to impress the local royalty.

A heartbreaking chain of events are set in motion when Gina goes into premature labour after she is caught in the crossfire of a punch-up in the Aidensfield Arms, whilst Merton is delighted when his team seize the chance to bring a major drugs operator to justice, but one of the officer's oversteps the mark when they develop a personal grudge against the LSD dealer.
