Saul Arkwright walks his dog close to Lord Ashfordly's estate when the dog is shot by one of Lord Ashfordly's guests Oliver Langley. Since Langley just drives off nearly hitting Arkwright in the process the latter see no other alternative than to make a complaint to the police. When the police do not do enough in his opinion Arkwright takes matters in his own hand. Vernon Scripps has had a new "bright" idea. He has bought a surplus U.S. Army half-track tank to drive tourists around the countryside. But since he has a boil in a very private place David has to drive the half-track for him. David only flattens half the village trying to get the hang of it.

Andrew and Beth Jarvis have been to a party for all the children in Aidensfield, but after the party their mother Linda does not show up to collect them. As a matter of fact neither she nor her husband have been seen since she had the family Land Rover filled up and serviced at Bernie's garage. Till they are found Dr. Merrick and Jenny take care of the children while Nathaniel Clegghorn keeps Phil Bellamy and Gina on their toes looking after the livestock. But they cannot go on indefinitely and Sergeant Merton organizes a search. Their neighbour Norma Weld may have an important lead. Speaking of Bernie's garage Vernon Scripps has a lot of plans for its future and invites Bernie to an expensive dinner at a posh hotel to discuss them. But Bernie is very satisfied with the way things are and will much rather be at home.
