The story of Phileas Fogg
Fogg makes a wager of £20,000 (£2 million in 2017) with members of London's Reform Club that he can circumnavigate the world in 80 days or less. He sets out with his French servant Jean Passepartout to win the wager, unaware that he is being followed by a detective named Fix, who suspects Fogg of having robbed the Bank of England. In the second half of the book Fix helps Fogg in order to get him back to the United Kingdom of Great Britain and Ireland, where he will be under British jurisdiction and Fix can arrest him.
While in India, Fogg saves a widowed princess, Aouda, from sati during her husband's funeral and she accompanies Fogg for the rest of his journey. Together, the trio have numerous exciting adventures which come to an abrupt end when he is arrested by Fix immediately upon their arrival back in England. Although Fogg is quickly exonerated of the crime, the delay caused by his false arrest appears to have cost him the wager. Soon, Fogg drew back his arm and punches Fix, while Passepartout cries, "Well hit!"
Believing himself ruined, Fogg returns home to ponder his options. Seeing his despair, Aouda, who has grown to love him and who feels guilty that he might have won the wager if he had not delayed to rescue her, proposes to marry him to help him cope with a difficult future. At this selfless offer, Fogg's reserve finally breaks and he joyously accepts Aouda's proposal. As it turns out, Aouda's gesture actually does save the day because as a result, Passepartout discovers that Fogg has miscalculated their travel time. Fogg did not take into account that because they crossed the Pacific Ocean from west to east, they gained a day when they crossed the International Date Line, and they have not missed the deadline after all. The three hurry off to the Reform Club and arrive just in time for Fogg to win the wager. Fogg splits his profits with Passepartout and Fix, and marries Aouda.
