As Fog, Rigodon and Tico begin their journey, Mr Sullivan hires a cunning saboteur called Transfer to stop them; Inspector Dix and Constable Bully also go after Fog believing he is a criminal.
Romy is searching for the uncle and aunt she has not seen for several years and traces them to Hong Kong. But, while she and the others are sailing there, they find themselves in the path of a typhoon.
Hong Kong is the last outpost of the British Empire Fog will pass through before returning to England, so Dix is determined to detain him there and tries to enlist Rigodon to help him.
Drugged by Transfer, Rigodon and Tico awaken to find themselves on the steamship Carnatic. Meanwhile, Fog and Romy search for another ship to take them to Japan.
Transfer leads a gang of outlaws in an ambush on a stage-coach whose driver has found the travellers on the prairie and agreed to take them to their destination.
Fog and the others cross the Great Lakes in an ice-boat. But, during the trip, Tico is taken ill, forcing the travellers to seek shelter in a log cabin until he has recovered.
Fogg believes he has lost it all, but Romy asks to marry him. And later Rigadon and Tico make a startling discovery that means one more race against time.
