Amanda attempts to forge a new partnership with Clive's headstrong young sheepdog and tragedy befalls the farm when 40-year-old Shetland pony Little Joe passes away. When ash dieback strikes, the family is forced to call in local fellow farmer Morris to help fell a decades-old tree and stop it collapsing onto a traditional stone barn. Using wood from the ancient tree, the children craft a headstone for Little Joe and help dad Clive lay the last of the earth on the pony's grave.
