Holy Warriors chronicles the spiritual upheaval brought about by war on those involved, offering profound insight into the resilience of the human spirit during trying times. It demonstrates the traumatic effect of enlisting unwilling soldiers in wartime, while raising the pertinent question of the links between war and religion, through these direct manifestations of fear and hate, love and faith in modern-day society. "There are no atheists in a foxhole," as one of the characters puts it.

Undesirables reveals how homeless youths and other marginal residents were swept out of Moscow by Russian police in preparation for high profile events, including the 1998 International Youth Olympics. The film follows the stories of four young runaways in different parts of Russia. Three of them ran away from their provincial homes to Moscow. The film depicts Moscow's juvenile detention center and documents the children's eventual deportation from the capital back to their abusive families or to reform schools in the provinces.

September 1, 1983 - a Korean Airlines 747, carrying 269 people, is shot down while flying through Soviet airspace. Everyone on board is killed, including 61 Americans. Twenty-three casualties were children under the age of twelve. The Soviets claim the plane was on a spy mission and that their actions were justified. The United States insists that Russia fired without provocation.

Join the Unsolved History team as they launch a new investigation into this tragedy, using technology and forensic science not available 20 years ago. Through careful re-examination of existing photographic, oceanographic and electronic records, experts set out to determine whether the KAL-007 disaster was simply a case of mistaken identity on the part of the Russian anti-aircraft - and whether flaws in the jet's navigational gear caused it to veer into unauthorized airspace. Plus, investigators look into the most puzzling aspect of all: Why was so little of the wreckage, including the remains of the passengers, found?

Director Davis Guggenheim eloquently weaves the science of global warming with Al Gore's personal history and lifelong commitment to reversing the effects of global climate change. “Al Gore strips his presentations of politics, laying out the facts for the audience to draw their own conclusions in a charming, funny and engaging style, and by the end has everyone on the edge of their seats, gripped by his haunting message,” said Guggenheim. An Inconvenient Truth is not a story of despair but rather a rallying cry to protect the one earth we all share. “It is now clear that we face a deepening global climate crisis that requires us to act boldly, quickly, and wisely,” said Gore.
