During a Thanksgiving dinner, professor Indiana Jones entertains his great-grandchildren by recalling a visit to China he made as a boy. While his father was working with the Chinese translator Yen Fu, young Indy, his mother and his tutor went sightseeing with their guide, Mr Li. After visiting the Great Wall of China, Indy fell ill during a rain storm and the travelers were taken in by a poor Chinese family. Dispite his mother's misgivings, she consented to have a local doctor treat her boy using acupuncture. 

While flipping through a gossip magazine at the supermarket, 93 year old Indiana Jones recounts his love affair with Mata Hari while visiting Paris on leave from the front in 1916. Unaware of Mata's involvement as a spy, 16 year old Indy became jealous when seeing her with other men, even though he admitted at the time that his feelings for Mata were not as strong as they had been for Vicky Prentiss in London five months earlier.
