This dark comedy is set in a 13th-century French monastery where the Abbott and his brother monks have fallen on hard times as the bones of Saint Foy, displayed on their altar, have not evoked a miracle for years, causing paying pilgrims to high-tail it off to a rival monastery, run by the Abbott's sister, where a duplicate set of bones, bought from a one-eyed, grave-robbing minstrel, are causing the blind to see, the lame to walk, and the coffers to overflow; the monks cross paths with said minstrel and are soon robbing their own cemetery for saintly bones to sell to the gullible faithful.
