When his brother disappears, Robert Manning pays a visit to the remote country house he was last heard from. While his host is outwardly welcoming - and his niece more demonstrably so - Manning detects a feeling of menace in the air with the legend of Lavinia Morley, Black Witch of Greymarsh, hanging over everything.

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.
