It's been three months since Marian's untimely death and Robin is a changed man. Tougher, he's sacked his gang since they all returned from the Holy Land. Not only that - he's hell bent on avenging his wife's tragic end. Her slayer, Guy of Gisborne is a marked man. 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.
