After he has celebrated his 40th birthday Tom decides that he is unhappy with his life style so he packs his job in, farms his large garden and becomes self sufficient.

The Goods install the first chickens in their chicken coop, but they prove slow to lay their first eggs. Incensed by the condescension of the Leadbetters when they are invited to dinner together with Tom's former boss & his wife, the Goods decide to sacrifice one of the chickens to make a show of their not being as poor as the Leadbetters think.

The Goods continue their bartering with local suppliers, but Barbara has a misunderstanding while negotiating with the window-cleaner. They then add a pair of pigs in a sty to their back garden, at which Margo is so appalled she brings in the chairman of the local residents' association to persuade them out of it, but is unsuccessful. However, when one escapes into the Leadbetter's garden, she can only be mollified by getting rid of it.

Tom puts the finishing touches to their own electricity generator in the cellar, which runs on their animals' waste. He then goes fishing with Jerry, and decides to store the surplus in the freezer, until the generator plays up...

In order to pay for a treat for Barbara, Tom takes a short contract from his old firm, and tries to keep it a secret from her - but his plan is foiled when he fails to account for Margo's nosiness.

While starting the harvest, Tom injures his back digging,and since Margo and Jerry are on holiday Barbara is left to look after the farm all on her own. A storm then adds to their problems by turning their garden into a mud bath.
