Serial killer Dennis Nilsen narrates his life and horrific crimes via a series of chilling audiotapes recorded from his jail cell. Set against the backdrop of 1980s Britain, when mass unemployment drew young men to London in search of their fortunes, only to find themselves destitute and easy prey, and weaving together interviews from police, journalists, survivors, bereaved families, and - for the first time the killer's own voice, this feature length documentary explores how Nilsen was able to get away with multiple murders and attacks, unchallenged, for five years.

Science may soon make the dream of traveling to Mars a reality, but how will we live once we get there? How will we manage our basic human needs of food, water, and shelter on a planet known for its barren surface conditions, high radiation levels, and toxic dirt?

The day of the Nazaré competition has arrived, and Garrett McNamara decides not to compete but instead support his long-time friend and teammate Andrew 'Cotty' Cotton. The competition does not go smoothly, with a major accident that has secondary effects on Cotty. After the competition, Garrett tries surfing at Nazaré again and realizes that can resume big-wave surfing. The episode concludes with retrospectives from a number of the surfers who appeared on various episodes throughout the season.

Twenty years ago, at 9.03am on 11 September 2001, America was under attack. President George W Bush was sitting in front of seven-year-olds in a classroom in Florida. Members of the president’s security detail thought the next plane could be aimed at them. The film is a claustrophobic clock-ticking thriller and tells the story of the presidency on arguably the most consequential day in recent history. As the clock ticks, the administration makes the greatest decisions of their lives: should they order fighter jets to shoot on American civilians? Should the president declare war or calm a battered nation? How would the leadership of the most powerful nation on earth grapple with the national and international implications?
This documentary tells the definitive story of the Bush administration through 12 hours of that momentous day, with first-hand testimony from President Bush, Vice-President Dick Cheney, National Security Advisor Condoleezza Rice and other senior staff who had their hands on the levers of power. The events of that day led to two decades of conflict in Afghanistan and Iraq. As America and its allies now withdraw from Afghanistan and the Taliban resume control, this is the story of how it all began.

Garrett also has misgivings about the state of safety plans at the competition, and tries to convince the organizers to beef up their plans.
