Scottish Highlands, 1823. The people of Glen nan Gall live by subsistence farming and illicit whisky distilling.

Twenty-year-old Fiona Gunn is the daughter of the chief smuggler; a small-made girl with a quick temper that hides her kind heart. After the militia march into the glen to put a stop to the distilling and smugging, Fiona befriends a young officer, Ensign Hepburn, who has been tasked with finding the smugglers.

Her mother has other plans, however, as she tries to match Fiona with a local man, Niall Grant. But it is not until she meets the landowner, Mr Gillespie, that Fiona's life really gets complicated.

With the glen and Fiona's family in turmoil, she is about to learn that there's more to people than meets the eye. But who is worthy of her heart?
