Davey Haggart is quite certain of his paternity (even if nobody else is) and determined to emulate his father, a notorious rogue and highwayman. This includes breaking a man out of Stirling jail, holding up the stagecoach, and robbing the Duke of Argyll, among other feats. Unfortunately, he is handicapped by the fact that his childhood playmate Annie is equally determined to track him down and save his soul.
