An organ grinder and his monkey launch an attack: the man is no less than Count Manzeppi, trying to gain a small wind-up bird toy. The toy contains the Philosopher's Stone, reputed to transmute base elements into gold. The race is on as West and Gordon track Manzeppi to his lair . After repeated setbacks and escapes, Manzeppi is forced to escape in a balloon while his henchwoman Gerda is transformed into a gold statue, and the bird and its stone are seemingly destroyed. At the end, the stone reconstitutes itself on the guys' train after they leave for the night.
