In an old castle live a young girl Isadora and her father Agrivaine, who is the guardian of a priceless treasure. Agrivaine forsees his own death in the Tarot cards, but it is a more immediate danger that troubles him. Raven, a one-eyed ruffian, together with Mortimer, Agrivaineís ex-steward, specialise in pillaging anything of value. Isadora seeks the help of Robin Hood.

Robin and the Outlaws make their way to Croxden Abbey to give away their loot to Abbot Martin - a fanatical monk and custodian of the Cross of Saint Ciricus, which is said to have healing powers. En route they come across a Lady, a victim of a robbery on her way to Croxden. Thinking she is about to die, the Lady makes a confession to Friar Tuck and reveals a strange connection between herself and Robin.
