The novel revolves around the military campaign of the Earl of Montrose on behalf of King Charles I against the Covenanters, who had sided with the English Parliament in the English Civil War. The main plot follows a love triangle involving Allan M'Aulay, his friend the Earl of Menteith, and Annot Lyle. Annot, who was captured during a blood feud and raised by the M'Aulays, eventually marries Menteith after her true lineage is discovered. This leads to jealousy and violence between M'Aulay and Menteith. A significant subplot features Dugald Dalgetty, a mercenary fighting for Montrose.
