When Turpin's friend Sam Morgan is thrown into jail by Spiker, Turpin and Swiftnick capture Sir John Glutton, hoping to exchange him for Morgan.

Sir John, worried by Turpin's growing popularity, decides to employ an imposter to pose as Turpin. His first victim is to be Amos Varley, Swiftnick's uncle.

Swiftnick acts in an impetuous manner, resulting in the capture of both himself and Dick Turpin.

Turpin and Swiftnick, hotly pursued by the Dragoons, run into old adversary Sir John Glutton; he now has a price on his head for treason.

The King's cousin is the only one to escape an attack by cruel highwayman Barnaby Husk. Fleeing into woods, he stumbles upon Isaac Rag, who leads him to 'the Fox'.
