After being falsely accused of murder, Sir Robin of Loxley takes refuge in the untamed wilderness of Sherwood Forest where he stumbles across a group of outlaws. Although initially suspicious of the aristocrat's motives, the men are soon won over by his integrity and prowess and Robin transforms them into a formidable fighting force, stealing from the rich and giving to the poor. As word of his fame and valour spreads, a legend is born.

When his brother disappears, a man visits the remote country house where he was last seen. While the host seems outwardly friendly and his niece more demonstrably so, there's a feeling of menace in the air with the overhanging legend of Lavinia Morley, the Black Witch of Greymarsh.
