After the death of Loxley, the outlaw band have gone their separate ways. Robert of Huntingdon, the man called by Herne, has rejected his calling, saying no one else could be The Hooded Man. He cannot escape his destiny. Robert's father, the Earl of Huntingdon, hosts a party to gain favour with vile, border lord Owen of Clun. Marion of Leaford attends with her father, who has bought her a pardon from the king. Clun makes unseemly advances toward Marion. When no one else will help her, Robert, to his father's horror, defends her in a swordfight against Clun. When Clun kidnaps Marion, Robert must reassemble the outlaw band to rescue her.

'Mad Mab' is an old hermit who lives happily with her family of pigs, including her 'baby', Rutterkin. Edgar of Huntingdon, Robert's uncle, captures Rutterkin and later Mab, accusing the old woman of being a witch (and the pig her familiar), paid by the Earl, Robert's father, to cause the death of King John, who has been beset by a mysterious illness. The Earl is arrested for treason and sentenced to death. In trying to rescue him, most of the outlaw band is taken as well.
