Indiana Jones describes to two truant boys his early life with his family and his dog. In Oxford 1908, Indy meets Helen Seymour, whom Henry requests to teach him on their voyage to Egypt. After an expedition to the pyramids, T. E. Lawrence invites Indy to the excavation of Ka's tomb, where he meets his friend Rashid, assistant to archeologist Howard Carter. The next day, Rashid is found murdered and the jackal headpiece stolen. Dimitrius, the chief blaster of the excavation, is revealed to be behind this, but he flees. In Mexico 1916, Indy is captured by Mexican revolutionaries, but is rescued by a Belgian called Remy. As Indy gets involved in the war, he recognises Dimitrius, who is collaborating with the US. After hearing how hypocritically the revolutionaries act, Indy and Remy decide to leave but not before Indy fights and defeats Dimitrius, to recover the jackal.

While having a meeting with his financier, Dr. Indiana Jones is reminded of the great love of his life, Vicky Prentiss. He met her in London in 1916 when she was working as a bus conductor and he was trying to pick up another woman (a war widow to be precise). Indy and Remy had just arrived to enlist in the Belgian army and were waiting to be send to La Havre for training.

Indy is at the Metropolitan Foundation for Educational Quality's Annual Celebrity Tennis Shoe Auction & Dinner, at the City Hotel & Conference Center. Two women sit at his table; one is an animal rights activist and vegetarian while the other holds opposing views. The two begin to fight, with Indy in the middle. He tells them that it reminds him of when he and his family were on his father's world lecture tour, and were invited to a coffee plantation in British East Africa that was owned by a friend of his father.

Indiana Jones (as Corporal Henri Defense) is working as a motorcycle courier for the French army. He has numerous close calls delivering orders to officers on the front line. When General Joseph Joffre gives Indy orders that will send men to certain death, Indy makes a courageous decision.

Indy (as Lieutenant Henri Defense) leads his Askari African soldiers to victory in an attack on an enemy stronghold and is promoted to Captain. His unit is sent across the Belgian Congo on an important mission, but most die of disease and exhaustion.

Being treated for a bee-sting to his toe, old man Indy recounts the time he spent in Albert Schweitzer's jungle hospital in Africa during the Great War. Schweitzer and his orderlies had picked up Indy and companions near death while attempting to bring a shipment of guns across the Congo. At first resistant to being treated by a German, Indy soon began to realize that Schweitzer was not interested in war, only attempting to cure people against all odds.
