Magnus leads an expedition to Hollow Earth to find her father and get answers; but they discover that figuring out the map was the easy part. Meanwhile Tesla and Druitt try to get some sense out of Adam.

With Adam loose in Hollow Earth Magnus is revived to answer for her supposed crimes, and quickly works out that Hollow Earth needs her help as much as she needs theirs.
