Jack, a former racing driver, and Harriet Boult, a nurse, live in a London flat with their two children, Frederica (Freddy) and Tom. Freddy suffers from asthma, which Harriet believes could be due to the city pollution, and after a serious attack begins to think leaving the city could be the best treatment available. Soon after, a letter arrives advising Harriet of an inheritance from one of her old patients, a run-down house in the country. It only takes one visit to persuade them to move.
The 18 episodes contain plots dealing with their adapting to life in the country and touches on environmental themes, alternative healing and alternative lifestyle choices.
The Boult family's country home, Meadows Green Farm, is sometimes said to have been in the Cotswolds, though place names mentioned in the series point to it being further south in Somerset. For example, the fictional address of Geoff Bate's Handcross Garage is Handcross, Somerset, and Shepton is mentioned frequently, presumably a reference to Shepton Mallet. The exact location of the house is at Tunley, two miles southeast of Bisley, near Sapperton, Gloucestershire.
A scene in the first episode of series two was filmed at Furze Platt Senior School in Berkshire.
