When Lady Hulton's cat falls ill, Siegfried embarks, with typical zeal, on updating the practice to cater for such refined clients. Lady Hulton, however, catches him out at every turn. James' problems lie with an affable but lazy farmer, Vernon Harker, whose plans to save himself from work even extend to marrying a tower of strength with a grown son to match.

Jenny Garston and David Rayner, individually charming farmer and horse-breeder, have been sworn enemies since their earliest school days. When a triple birthday is marred by tragedy it falls to Siegfried to negotiate with the stony-faced neighbors.
