Our old friends newlyweds Mel and Martin Irvine return to the series and introduce their newest member of the family, four-month-old Erin. In Fife, buffalo farmer Stevie must select a new breeding bull from hisherd. Highland crofters Robin and Penny chase a runaway calf and Alastair has to leave Janet alone on Mull while he travels to the mainland to take an important deer-stalking test.

As winter arrives, Stevie experiments with a radical buffalo feeding idea, David is anxious to find out if his cows are in calf, dairy farmers the Roan family set up a milkshake stand at the Dalbeattie Christmas lights-on event and Robin and Penny's family arrive in the Highlands for the annual festive ceilidh.
