Although it's 90 years since the end of WW1, the feud between the Hammond and Hicks families still festers. Much to the disgust of Colonel Henry Hammond, Private Tommy Hicks condemned for cowardice in the conflict, has been exonerated and his name added to the local war memorial. Meanwhile Barnaby is not a happy man. His roof is leaking and his peaceful dinner with Joyce at the local hostelry is interrupted when he has to break up a fight between the two elderly patriarchs of the Hicks and Hammonds families who, despite being wheelchair bound, battle it out with baguettes!
