Even 2,000 years after his death, General Hannibal's battle strategies are still studied today. But of all his military feats, perhaps his greatest was leading his massive Carthaginian army of men and three-dozen elephants across the Alps and into the heartland of Rome in 218 B.C. Until now, the route they took has been a matter of dispute, but thanks to modern-day technology, geomorphologist Bill Mahaney and microbiologist Chris Allen believe they've accurately traced this ancient journey.

An intimate portrait of Malala Yousafzai, who was wounded when Taliban gunmen opened fire on her and her friends' school bus in Pakistan's Swat Valley. The then 15-year-old teenager, who had been targeted for speaking out on behalf of girls' education in her region of Swat Valley in Pakistan, was shot in the head, sparking international media outrage. An educational activist in Pakistan, Yousafzai has since emerged as a leading campaigner for the rights of children worldwide and in December 2014, became the youngest-ever Nobel Peace Prize Laureate.

The second episode tells the story of the trial of Hermann Goering, Hitler's charismatic and ruthless second-in-command. On trial for his life at Nuremberg, the unrepentant Reich Marshal turned the tables on the Allies. So much so that Chief Prosecutor Justice Robert Jackson began to wish the Allies had followed Churchill's suggestion and shot the leading Nazis out of hand. This documentary drama traces the behind-the-scenes story of Goering's attempt to re-ignite Nazism from the courtroom.

This episode explores the wave theory of light as studied by mankind, noting that light has played an important role in scientific progress, with such early experiments from over 2000 years ago involving the camera obscura by the Chinese philosopher Mozi. Tyson describes the work of the 11th century Arabic scientist Ibn al-Haytham, considered to be one of the first to postulate on the nature of light and optics leading to the concept of the telescope, as well as one of the first researchers to use the scientific method. Tyson proceeds to discuss the nature of light as discovered by mankind. Work by Isaac Newton using diffraction through prisms demonstrated that light was composed of the visible spectrum, while findings of William Herschel in the 19th century showed that light also consisted of infrared rays. Joseph von Fraunhofer would later come to discover that by magnifying the spectrum of visible light, gaps in the spectrum would be observed. These Fraunhofer lines would later be determined to be caused by the absorption of light by electrons in moving between atomic orbitals when it passed through atoms, with each atom having a characteristic signature due to the quantum nature of these orbitals. This since has led to the core of astronomical spectroscopy, allowing astronomers to make observations about the composition of stars, planets, and other stellar features through the spectral lines, as well as observing the motion and expansion of the universe, and the existence of dark matter.

Fights within Eagles were common long before Hotel California. They started as four equal partners. Gradually the power shifted toward Henley and Frey, which Meisner and Leadon resented. Leadon left first because the band progressed from country to rock. He also wanted to live a healthy life in a band that lived extremely unhealthy. Even though they made many wonderful songs, things were far from smooth in the studio.

In 1962 Hitchcock and Truffaut locked themselves away in Hollywood for a week to excavate the secrets behind the mise-en-scène in cinema. Based on the original recordings of this meeting-used to produce the mythical book Hitchcock/Truffaut-this film illustrates the greatest cinema lesson of all time and plummets us into the world of the creator of Psycho, The Birds, and Vertigo. Hitchcock's incredibly modern art is elucidated and explained by today's leading filmmakers: Martin Scorsese, David Fincher, Arnaud Desplechin, Kiyoshi Kurosawa, Wes Anderson, James Gray, Olivier Assayas, Richard Linklater, Peter Bogdanovich and Paul Schrader.
