Jack Frake and Hugh Kenrick resign themselves to the likelihood of war with the Crown. Hugh returns to England on urgent personal business, while Jack prepares for the coming conflict. In the meantime, Jared Turley, an agent of Earl Basil Kenrick, posing as a Customs official, sets his sights on Hugh Kenrick to punish in the name of his employer. He allies himself with the detested new royal governor of Virginia, Lord Dunmore, and confiscates the Sparrowhawk.
Jack Frake and his men march to Boston and Bunker Hill. And during a final battle on the York River in Virginia against the Sparrowhawk, Jack must again face an agonizing choice, one he had made in Falmouth, England, years before.
