A market traders van is hijacked and stolen on the moors. Nick starts to investigate and suspects Lord Ashfordly's son, who he later arrests for drink driving. Kate unintentionally starts a chicken pox epidemic when she starts a mother and baby group. Nick spots Claude wearing a brand new pair of boots several sizes too small which turns out to be part of market traders stolen stock. However, he doesn't think Claude is involved, but Blaketon disagrees. A local girl is pregnant and confides in Kate as to whom the father is. Nick later identifies the hijacker as Lord Ashfordly's new chauffeur, who also turns out to be the father of the local girl's baby.

An elderly widower, a Mr. Miller from London comes and stays in the village and stays in a boarding house opposite the police house run by Mrs. ?. Milner however is not a well man and has to visit Kate at the surgery. Meanwhile Claude has been asked to do a barn clearance, and Nick buys the remains of an old MG off him for only £25. Claude dramatically underestimates its real value and is later annoyed by this, and complains to Blaketon. Milner it seems has an old grudge against Nick and he wants his revenge. It turns out that when Nick was down in the Met he arrested Milner's granddaughter after she stabbed her husband in self defence. Milner now wants to hurt Nick, the way Nick hurt him. He takes Kate as a hostage and is armed with a pistol. Kate manages to talk Milner round because she has to rush off to give a young girl a vital injection.

A German American called Victor Kellerman arrives in the village with the intention of killing a local landowner, a Mr Lessor. He attacks Lessor but he cannot go through with it and leaves the area. Kellerman is later arrested and Nick is assigned to escort him back into the area. It is revealed that Lessor was a SS traitor and responsible for sending Kellerman and his family to Nazi concentration camps during WW2. Meanwhile Kate is treating Lessor for diabetes, and when he realises he will have to go to court he takes an over dose of insulin. Without him the evidence is incomplete and the charges are dropped. Tragedy strikes when Dr Alex Ferrenby drowns whilst fishing, he died of a brain hemorrhage. And Greengrass helps some gypsies organise some bare-fist fighting.

Inspector Crossley from Whitby arrives at the police house to see Nick, but is angry to find the police house being used as a doctor's surgery by Kate. Crossley then goes to Ashfordly station where he's been expected expressing his annoyance about the situation. Blaketon and Nick both assure him however it's just a temporarily situation until Kate can find a new surgery. Crossley also informs Blaketon of some major changes in the Ashfordly area, which will include a far bigger beat for Nick. Kate in the meantime goes out with her old friend Sally, who's also a GP for a drink and a general chat. Sally tells Kate of a job that's going in Whitby, but Kate isn't interested. Sally then puts Kate's name forward to a Dr. James Radcliffe who owns his own practice in Whitby. Radcliffe writes to Kate offering her a job with his practice and Kate is then tempted to take him up on his offer, but Nick however is reluctant to leave Aidensfield. A coach trip meanwhile is organised to hear Gina sing a
