England, 1685. Decades after the end of the civil war, the country is once again divided when Charles II's illegitimate son, the Protestant Duke of Monmouth, arrives in Dorset to incite rebellion against his Catholic uncle. Armed only with pitchforks, Monmouth's army is quickly defeated by King James II's superior forces and charged with high treason. Those found guilty will be hanged, drawn and quartered. As Dorset braces for carnage, the redoubtable Lady Jayne Harrier and a small group of trusted allies - including her courageous son and the independent-minded daughter of a local lawyer - contrive ways to save men from the gallows.
