The boyhood adventures of the greatest action hero of all time: Indiana Jones. Young Indy travels the world, meeting some of the greatest figures of the early 20th century, and participating in the events that helped shape history.

In the twentieth film in the series, in 1950's Wyoming, middle-aged Indiana Jones and his friend Grey Cloud have obtained a sacred ceremonial pipe and end up in a snow-logged cabin. When Jones uncovers a soprano sax, he is reminded of his college days in 1920's Chicago, waiting tables at Colosimo's restaurant and becoming obsessed with Jazz music. When Colosimo was murdered, young Indy got caught up in the investigation together with his roommate Eliot Ness and young reporter Ernest Hemingway.

At the dawn of the 20th century, Indiana Jones discovered the world. From globetrotting family expeditions as a 9-year-old to the battlefields of World War I as a teenager, Indy’s experiences shaped the heroic, whip-cracking archaeologist he would become. At every turn, Indy encounters history in the making, meeting true-life activists, soldiers, writers, artists, and thinkers who helped influence the world we live in today.
