The story takes place just before the Jacobite rising of 1715, with much of Scotland in turmoil.Frank Osbaldistone, the narrator, quarrels with his father and is sent to stay with an uncle, Sir Hildebrand Osbaldistone, in Northumberland. Frank falls in love with Diana Vernon, Sir Hildebrand's niece, whose father has been forced to go into hiding because of his Jacobite sympathies. Frank's cousin, Rashleigh, steals important documents vital to the honour and economic solvency of Frank's father, William, and Frank pursues Rashleigh to Scotland. Several times his path crosses the mysterious and powerful figure Rob Roy MacGregor, known as Rob Roy, an associate of Sir Hildebrand. The eponymous Rob Roy is badly wounded at the Battle of Glen Shiel in 1719, in which a British army of Scots and English defeat a Jacobite and Spanish expedition that aimed to restore the Stuart monarchy. All of Sir Hildebrand's sons but Rashleigh are killed in the Jacobite rising, and Rashleigh, too meets a bloody end. Following this, Frank inherits Sir Hildebrand's property and marries Diana.
