When a young German man arrives to visit his father's grave, the residents of Aidensfield are outraged as his father dropped a bomb on the village during the war, killing two popular residents. Nick and Bellamy intervene when the victim's thuggish son sets out to avenge his parents' death. Meanwhile, Greengrass disappears after taking a hen-pecked husband on a drinking binge, causing panic in the village and a search party to assemble, whilst Maggie puts the past behind her.

Ventress' sanity is called into question when he reports of a UFO sighting on the moors during a thunderstorm, leaving Nick with the task of fighting for the veteran's future in the force and to play peacemaker between two feuding neighbour's. Meanwhile, Greengrass is delighted to win a holiday cruise, until a trip to Whitby reveals he suffers from sea-sickness. However, he quickly spots a way to make money by selling the tickets to a businessman planning to his escape with his mistress, whilst Eileen learns a valuable lesson when her charity collection is stolen.
