A much darker and tougher Robin returns from the Holy Land, and now there’s only one thing on his mind – to avenge Marian’s death and punish her murderer, Guy of Gisborne (Richard Armitage).
Upon his arrival back in England, Robin breaks with his followers, and races to Locksley Manor to confront Gisborne, but does Gisborne even care whether he lives or dies now that Marian, the only woman he’s ever loved, is gone?
Meanwhile, the wickedness of the Sheriff (Keith Allen) continues unabated. He’s sold the local men to fight a foreign war and when a feisty Locksley girl, Kate (Joanne Froggatt, Life On Mars), objects to her brother’s forced conscription, she inadvertently gets caught up in the cause of Robin Hood and becomes an indispensable member of the gang.
The third season also brings an unexpected addition when Gisborne’s little sister, Isabella (Lara Pulver), arrives and further complicates the lives of both Robin and Gisborne. And, as the threat of Prince John (Toby Stephens, The Queen’s Sister, Waking the Dead) looms ever larger, Robin and Gisborne reach an uneasy truce and soon realize they may have more in common than they originally thought.
