Egypt on the Brink: Arab Spring climaxed in the overthrow of President Mubarak in Egypt. But for many Egyptians, the situation has actually gotten worse. China's Ghost Towns: Fifteen years ago, China changed its policy so people could buy their own homes. Real-estate investments boomed, and new cities began popping up. The problem is: people don't live in what have become 'ghost cities.'

Widespread immigration to the U.S. from Latin countries begins – first with a small group from Cuba, then a larger one from Mexico. Both flee chaos and violence in their home country and are attracted by opportunities in the United States. In 1898, the U.S. helps liberate Cuba and Puerto Rico from Spain but then seizes Puerto Rico as its colony. The first Puerto Rican arrivals (now U.S. citizens) establish a network in New York.

This second instalment looks at how Vladimir Putin arrived in the Kremlin as a vulnerable and unknown president, whom the Russian oligarchs expect to control. The programme reveals how he asserted his hold on power and ultimately surrounded himself with his KGB peers, as well as his philosophy as regards traitors and enemies. The film also examines the stories of businessman Boris Berezovsky and defector Alexander Litvinenko, who both stood up to Putin and wound up dead on British soil.

North Koreans cross the border into China illegally every year, some via a modern-day underground railroad to freedom and eventual citizenship in South Korea. VICE visits the most dangerous place in the world: Kashmir's line of control, which partially occupies the Indian state and separates India from Pakistan.

This episode covers the European refugee crisis, the largest refugee migration since World War II. Following the refugees on their journey, Vice sets out to cover not only the trials of those seeking asylum from the Syrian conflict, but the reactions from the Western world and the countries that have sought to take them in. Unfortunately, but perhaps not surprisingly, the response in many regions has been oppositional, especially in the aftermath of the Paris and Brussels ISIS attacks. In addressing this modern world crisis, Vice depicts the severe trials and tribulations faced by the desperate refugees, and the consequences, noticed or unnoticed, of turning them away.

Dr Hannah Fry travels down the fastest zip wire in the world to learn more about Newton's ideas on gravity. His discoveries revealed the movement of the planets was regular and predictable. James Clerk Maxwell unified the ideas of electricity and magnetism, and explained what light was. As if that wasn't enough, he also predicted the existence of radio waves. His tools of the trade were nothing more than pure mathematics. All strong evidence for maths being discovered.
But in the 19th century, maths is turned on its head when new types of geometry are invented. No longer is the kind of geometry we learned in school the final say on the subject. If maths is more like a game, albeit a complicated one, where we can change the rules, surely this points to maths being something we invent - a product of the human mind. To try and answer this question, Hannah travels to Halle in Germany on the trail of perhaps one of the greatest mathematicians of the 20th century, Georg Cantor. He showed that infinity, far from being infinitely big, actually comes in different sizes, some bigger than others. This increasingly weird world is feeling more and more like something we've invented. But if that's the case, why is maths so uncannily good at predicting the world around us? Invented or discovered, this question just got a lot harder to answer.
