In the fourth part of the series, Diarmaid MacCulloch makes sense of the Reformation, and of how a faith based on obedience and authority gave birth to one based on individual conscience. He shows how Martin Luther wrote hymns to teach people the message of the Bible, and how a tasty sausage became the rallying cry for Swiss Reformer Ulrich Zwingli to tear down statues of saints, allow married clergy and deny that communion bread and wine were the body and blood of Christ.

When the rumoured whereabouts of Osama bin Laden are revealed, the CIA readies a team of seasoned U.S. Navy Seals for the mission of a lifetime. Despite inconclusive evidence that bin Laden is inside the compound, and ignoring the possible ramifications of an unannounced attack on Pakistani soil, the Pentagon orders the attack. The Seal Team bands together to complete their mission of justice in a riveting final showdown.

Privately, he was humble, almost shy, and fiercely patriotic, donating millions to his native Brazil and contemplating a life beyond motor-racing. Yet he is struck down in his prime on the blackest weekend in the history of the sport, watched live on television by 300 million people. Years on he is revered in Formula One as the greatest motor racing driver of all time - and in Brazil as a Saint.

The sun gives us warmth and light. It is the fuel of life. Without the energy of the sun almost nothing grows, thrives or lives. But the sun was not put there for our benefit. It is not this big jolly ball of nice smiling down on us, wishing us all a good day. It is not our friend. The sun is a monster. A planet killer. And we don't see that side of the sun down here.
But eight astronauts, with over 1,000 days in space between them, can show us how being up there helped them understand the suns bright fury.

The honey badger looks like something you might buy in pet shop and give to children, but turns out to be one of the most violent and determined creatures ever to scuttle across the face of the earth. Nothing in the badger’s world-not even the badgers themselves-are safe from its remarkable ability to create havoc and cause harm. Like a meter long skunk with the brain of a shark the Honey Badger’s metabolism compels it to eat constantly and live on the run. Its diet is admirably inclusive ranging from insects to its own young. If an animal is too big to eat then the badger will fight it anyway, indeed it is this almost supernatural tenacity that compels you respect it, as well as yielding some of the most spectacular sequences in the film. Five foot long cobra sleeping in the top of tree? No problem, the badger scoots up and bites its head off. When an ailing badger is attacked by a full size leopard it takes the leopard over an hour to finish it off. When one is bitten in the face by a snake that can kill a man, it just lies down for a while and sleeps it off.

Reveals the events behind KURT COBAIN's death as seen through the eyes of Tom Grant, the private investigator that was hired by Courtney Love in 1994 to track down her missing husband Kurt only days before his deceased body was found at their Seattle home. Cobain's death was ruled a suicide by the police (a reported self-inflicted gunshot wound), but doubts have circulated for twenty years as to the legitimacy of this ruling, especially due to the work of Mr. Grant, a former L.A. County Sheriff's detective, who did his own investigation and determined there was significant empirical and circumstantial evidence to conclude that foul play could very well have occurred.
The film develops as a narrative mystery with cinematic re-creations, interviews with key experts and witnesses and the examination of official artifacts from the 1994 case.
