It's Christmas with the Greens, and this year is extra special because it's Steve's 80th Christmas on the family farm. Although he's not as mobile as he used to be, Peter is determined to make sure it's their best Christmas ever by doing all he can to assist with preparations. He helps with tree choosing, decorating and shopping, although he hands over cooking with Jean duties to his wife Lin! Peter even helps Steve and Jean make their own crackers and create a very special festive card (using a green screen, of course) as these three old friends reminisce about Christmases past, enjoy the present and look to the future. 

Peter Wright is called to Stoneybrough Farm to take a look at Reuben, the Greens' ten-year-old collie-cross-whippet, who's been struggling with arthritis. And Steve and Jean have an ‘in-tents' experience when they explore the world of glamping with a little help from their old friends Rob and Dave Nicholson from Cannon Hall Farm.

We also meet the Greens' three trusty (and rusty) old tractors, one of which is exactly the same age as Jean herself. Peter hopes to be able to drive one of them, the Silver Dream Machine, in a charity tractor run that he's organising, but will the old girl be up to the task?

And it's party time on the farm as Steve celebrates his birthday with friends and family – and a giant pork pie. As the party dies down, Peter whisks Steve and Jean away to experience what it's like to be stars of the big screen, before taking them for a very special picnic at the couple's favourite beauty spot.

Jean takes Peanut, the oldest of her 13 cats, to Peter's surgery for a check-up and rewards the ageing moggie with a luxury cat tree. Away from the farm, daughter Sarah dons her L plates and takes her parents out in the car for the very first time. The Greens also have the experience of a lifetime when vet Matt Smith treats them to a day at a nearby wildlife park.

Jean gets to see her farm from above when Peter Wright takes her on the helicopter ride of a lifetime, while the Greens receive a visit from an estate agent, who surprises them with just how much money they could make by selling some of their 25-acre estate. Plus, Steve and Jean are busy chopping firewood with the help of Jean's younger brother.

The Greens reminisce about when they had to sell their herd of milking cows and Peter Wright treats their calf for a case of ringworm. Plus, Matt Smith visits a younger North Yorkshire farmer to check on one of his pregnant longhorn cows.
