Robin is a changed man, swearing vengeance against Guy of Gisbourn. Fuelled by anger and grief, Robin seems stuck in a downward spiral, but a new beacon of hope arrives in the form of a travelling monk called Tuck (David Harewood), who soon gets our hooded hero back on track. Meanwhile, the wickedness of the Sheriff continues unabated. A spirited Locksley girl named Kate (Joanne Froggatt) objects to her brother's forced conscription. As a result she inadvertently gets caught up in the cause of Robin Hood and becomes an indispensable member of the gang. As the threat of Prince John (Toby Stephens) looms larger, Robin and Gisborne have to reach an uneasy truce as it emerges that they may have rather more in common than they thought.
