Amidst a government budget that sends the UK farming community into uproar, Jeremy decides some big changes are needed to make the farm run more smoothly. But while the farm tries to go high-tech – resulting in Kaleb's first ever trip abroad – even bigger developments are heading for Diddly Squat that are going to prove much more of a challenge.

Jeremy is taking on his most ambitious project yet, setting out to buy a pub that will reignite his Farm to Fork restaurant vision. But the road to becoming a landlord isn’t exactly straightforward, and with new faces, new livestock and new machinery arriving at the farm, life at Diddly Squat is busier than ever.

Another year in the life of Diddly Squat Farm, run by Jeremy Clarkson, Britain's best-known but least-qualified amateur farmer. In an effort to increase his annual profit (£144 last year) he's diversifying, in the shape of cows, more chickens and his own restaurant.

After the triumphant finale of Season 2, we return to Diddly Squat to find everything in turmoil. The council has shut the restaurant and the weather is ruining the crops. Desperate for new income streams Jeremy enters a world of pig breeding, goat attacks and mushroom mountains. Meanwhile Kaleb, promoted to farm manager, deals with an unwelcome rival. The funniest, most heartbreaking season yet.
