On his 40th birthday, Tom Good decides that he's had enough of the rat race, and that he and his wife Barbara should become self-sufficient. Overnight they begin to convert their suburban garden into a farm, complete with crops, pigs and chickens, homemade beer and more. But their choice of lifestyle doesn't exactly fit in with the neighbours, in particular Margo Leadbetter and her henpecked husband Jerry who find themselves hindering, but even sometimes helping against their better judgement.
