The turmoil of 1968 helps Nixon win the presidency. Troop strength in Vietnam peaks and the draft accelerates. Karl Marlantes endures bitter jungle fighting on Hill 484, and draftee Arthur Wiknik gets a grim introduction to combat on 'Hamburger Hill'. But shortly after winning both hills, US troops abandon them.

The enemy gains ground when the massive Tet Offensive catches the Americans by surprise. At Khe Sanh and Pleiku, U.S. troops are under siege. Americans mount a counteroffensive but the shock of the assault ignites anti-war fervour at home.

A look at the probes which explored our Solar System, laying the groundwork for a future spacecraft to search for life on a second Earth. That space craft must communicate, it must navigate, it must have power, it must have propulsion. We will have to give it all the intelligence necessary to make its own decisions. In 'The Explorers' the spacecraft Artemis initiates launch sequence and begins its 4.7 light year journey to Minerva B - an Earth-like exoplanet.

The next great voyage of human exploration has already begun: the search for life on planets orbiting distant stars. With extraordinary CGI, the world's most inspiring scientists, via extreme environments on Earth and around the solar system, the film takes viewers aboard the next generation of space ships, across the cosmos and beneath the clouds of the exo-planets to discover The Living Universe.
Part 1: 'The Planet Hunters' For as long as we’ve had eyes to see and minds to wonder we’ve marveled at the stars. Since the discovery of the first so-called exoplanet in 1994, the Planet Hunters have transformed the way we see the universe. It is the year 2157, and spacecraft Artemis enters the final phase of construction.

American troops launch widespread 'search and destroy' operations; body count, not territory, becomes the measure of success in Vietnam. Charles Brown fights for survival on the bloody slopes of Hill 875 and at home, the American public begins to question U.S. military strategy.

Vintage footage from the Vietnam war is presented along with narration from both war veterans and Hollywood voice talent. The documentary follows key events and their impact on both the war effort and the American public.
The Beginning: The first episode looks at the early months of the Vietnam war from the escalation following the Gulf of Tonkin incident to the grim fighting of the Battle of Ia Drang where a few hundred American soldiers are pinned down by three battalions of North Vietnamese infantry. Using superior air power and reinforcements, the Americans fight the North Vietnamese to a draw.
