A duke forces a witch to call up his ancestor so that he can ask the ghost where the castle's hidden treasure is. When the witch does as she is bidden, the ghost replies that the treasure location was a secret even in his time and that the duke will have to seek further back. The witch calls up several spirits in succession without the knowledge of the treasure's location until she calls up a gorilla which strangles the duke.
