Until World War II, Latino immigration to the United States was overwhelmingly Mexican-American. Now three new waves bring large-scale immigration from Puerto Rico, Cuba, and the Dominican Republic. As the Puerto Rican government implements a historic overhaul over a million Puerto Ricans are encouraged to leave for the US mainland, to alleviate the economic pressure. A young Juanita Sanabria arrives in New York, works hard in the garment district, but encounters hostility and discrimination. Ethnic tensions explode in youth gang warfare depicted in films like West Side Story, etching the stereotype of the knife wielding Puerto Rican in the American consciousness.

Many movies lend themselves to dramatic interpretations, but none are as rich and far ranging as Stanley Kubrick's The Shining. In LA filmmaker Rodney Ascher's ROOM 237, we hear from people who have developed far-reaching theories and believe they have decoded the hidden symbols and messages buried in the late director's film. Carefully examining The Shining inside out, and forwards and backwards, and backwards and forwards, ROOM 237 as captivating, provocative as it is pure pleasure". It gives voice to the fans and scholars who espouse these theories, reworking the film to match their ideas and intercutting it with layers of dreamlike imagery to illustrate their streams of consciousness. Sometimes outrageous, always engaging, the words of those who were interviewed are given full force by Ascher's compelling vision. Also featured at the 2012 Sundance, Cannes and Toronto film festivals.

Julien Temple's epic time-travelling voyage to the heart of his hometown. From musicians, writers and artists to dangerous thinkers, political radicals and above all ordinary people, this is the story of London's immigrants, its bohemians and how together they changed the city forever. Reaching back to the dawn of film in London at the start of the 20th century, the story unfolds through film archive, voices of Londoners past and present and the flow of popular music across the century; a stream of urban consciousness, like the river which flows through its heart. It ends now, as London prepares to welcome the world to the 2012 Olympics.

We live our lives pursuing happiness 'out there' as if it is a commodity. We have become slaves to our own desires and craving. Happiness isn't something that can be pursued or purchased like a cheap suit. This is Maya, illusion, the endless play of form. In the Buddhist tradition, Samsara, or the endless cycle of suffering is perpetuated by the craving of pleasure and aversion to pain. Freud referred to this as the "pleasure principle." Everything we do is an attempt to create pleasure, to gain something that we want, or to push away something that is undesirable that we don't want. Even a simple organism like the paramecium does this. It is called response to stimulus. Unlike a paramecium, humans have more choice. We are free to think, and that is the heart of the problem. It is the thinking about what we want that has gotten out of control. The dilemma of modern society is that we seek to understand the world, not in terms of archaic inner consciousness, but by quantifying and qualifying what we perceive to be the external world by using scientific means and thought. Thinking has only led to more thinking and more questions. We seek to know the innermost forces which create the world and guide its course. But we conceive of this essence as outside of ourselves, not as a living thing, intrinsic to our own nature. It was the famous psychiatrist Carl Jung who said, "one who looks outside dreams, one who looks inside awakes." It is not wrong to desire to be awake, to be happy. What is wrong is to look for happiness outside when it can only be found inside.

Everyone from the most simple-minded to the deepest thinking has pondered a question that strikes at the core of our existence: Is there life after death? What happens to the soul after we die? People who have had near-death experiences claim to have visited the other side before getting yanked back into consciousness. Now, some of the brightest minds in science are trying to understand how life can persist beyond the physical and what will it look like. It might be a quantum state based on the fundamental laws of the universe. Ultimately, it is a journey that struggles to decode the most complicated instrument in the universe: the human brain.

Professor Marcus du Sautoy goes in search of answers to one of science's greatest mysteries: how do we know who we are? While the thoughts that make us feel as though we know ourselves are easy to experience, they are notoriously difficult to explain. He has his mind scrambled by a cutting-edge experiment in anaesthesia. After, Marcus is given an out-of-body experience in a bid to locate his true self.
