The New Adventures of Robin Hood S01 E08 Witches of the Abbey

Three beautiful, evil witches take Little John captive, and make him their slave. Robin's band cannot breech the catacombs of the abbey where the witches have taken him, because of the powerful magic they practise. Robin uses a magic potion from Friar Tuck to fake his own death, knowing that his evil Aunt Alice, the Abbess, will entomb him in the family crypt inside the abbey. He thus gains entry to rescue Little John and vanquish the witches.
