It's Indy's first encounter with love. Even though he's got advice from the best experts Vienna has to offer on that subject -- Freud, Jung, and Adler -- he's not prepared for the excitement. He soon finds himself hanging from carriages, scaling walls, risking guard dogs, and avoiding an overprotective governess to be near his beloved Sophie. But Sophie's not only the object of Indy's affections; she's also the daughter of Archduke Ferdinand, the ruler of the Austro-Hungarian Empire.
