Lady Lairds follows the trials, tribulations and successes of four women over a year as they run their Scottish Highland estates and country houses. Joanna moves up from her successful career in London to take over running the huge Attadale estate from her parents, and with a house full of guests, she is thrown in at the deep end at the Highland games. At Loch Fyne, Lady Laird Tuggy faces a major test to see if her new brewery is up to standard, and at the Auchlyne estate, Emma is making sure every lamb is gathered from the hills for the market as daughter Emma tries to find extra money-making opportunities.
