In an unsettling time following Jacobite Rebellion of 1745, Ewen Cameron of Ardroy is living in Scottish Highlands by his beloved loch with his wife and two young boys. When his younger son falls in the cold loch water, he gets rescued in the last minute and falls ill, so Ewen goes strolling through hills and moors looking for someone who can help his boy. However, King George's Redcoats are patrolling through the Highlands, assisted by local clan spies, lurking to catch mutineers from the Rebellion. Ewen gets captured and taken to London to be executed where he crosses paths with his old friend Keith Windham, former Captain of the Royal Scots.
