The Sundarbans mangrove forest, in Bangladesh near the Indian border, is a tidal jungle where Ganges and Brahmaputra enter the Indian Ocean. Its has some 400 Bengal tigers - the largest population in the world, and the only to be hardly scared of men. The downside is tigers kill up the 50 Bangladeshis a year, even from neighbouring villages, so keeping them inside the reserve is key to long-term survival.
A recent project tries to train local mongrels, not pets but fiercely self-reliant dogs, to spot and even scare off tigers from villages. An individual tiger can turn into a man-eater in order to survive - this process may occur due to an injury or old age (and so cannot hunt agile prey) or even accidentally tasting human flesh.

We call them 'man’s best friend', but their story is almost as old as man himself. Our very first friend in the world, they have walked by our side for over 20,000 years, helping us to hunt for food and offering us companionship and protection. Man’s First Friend is an epic new primetime documentary event that combines natural history, science and anthropology to explore the enduring relationship between humankind and dogs, how the two species have co-evolved together, where did they come from to take such a prominent position in our lives, and how did we learn to harness their unique talents.
The film takes viewers on an extraordinary journey through some of the most remote locations in the world to answers these questions and more. It highlights what dogs are capable of: from the Pariah dog in India who protects her owner’s banana plantations from daily attacks by Black-headed Monkeys; to Kenyan Bloodhounds trained to track ivory poachers. Dogs comfort us, relieving loneliness and helping us cope with old age.

The film goes deep beneath the surface to explore the lives of man's greatest parasite. Morgan Spurlock unveils a new form of documentary horror storytelling, journeying around the world to bring viewers face to face with rats while delving into our complicated relationship with these creepy creatures. Taking us into the rats nests in ways never before captured on film, RATS dives deep into New York City's parks, subway tunnels, and sewers; venture to rice paddies in Cambodia and Vietnam where rats are caught and sold as food, cross worldly streets in India paroled by the revered Night Rat Killers, journey to English countryside where packs of terriers kill hundreds of rats per day, and look inside a New Orleans lab, where scientists are studying how flooding and abandoned neighbourhoods are making rats more invasive than ever.

In 335 BC Alexander of Macedonia set off on an expedition to conqueror the world. The voyage of Alexander the Great covered more than 22,000 miles in ten years, from Greece to India and back, through some of the most difficult and unforgiving terrain. Michael Wood was hot on his trail, following, as closely as possible, in the footsteps of Alexander and the army that he drove to achieve the impossible. In this programme: the Lebanese city of Tyre, scene of Alexander's most desperate battle; the Palestinian legend of `Two-Horned Alexander'; and the Egyptian oasis of Siwa, where Alexander was proclaimed pharaoh and son of God.

American exchange student Amanda Knox is convicted and eventually acquitted for the 2007 death of another student in Italy. Was she a cold-blooded psychopath who brutally murdered her roommate or a naive student abroad trapped in an endless nightmare? Directors Rod Blackhurst (Tribeca Audience Award-winner Here Alone) and Brian McGinn (IDA Award-winner Chef's Table) and producer Mette Heide (Peabody Award-winner India's Daughter) explore the notorious case that made headlines around the world.

The documentary 'The Knowledge of Healing' is an illuminating examination of Tibetan medicine, a practice which has developed over two millennia into a modern day successful method of healing that rivals western medical practices. Unlike Western medicine, based on biochemistry, Tibetan medical thinking (which is strongly rooted in Buddhist principles) views the human body as governed by an elaborately organized system of energies flowing through a network of channels. In the 12th century, the Gyüshi (Knowledge of Healing) was created, a text codifying this intricate system. The medications used comprise herbs, roots, minerals, etc. After flourishing for centuries, most Tibetan medical schools were destroyed by the Chinese in the 1950's and 1960's, and many physicians were executed. Speaking from exile, the Dalai Lama argues for the value of Tibetan medicine, while his personal physician Dr. Tenzin Choedrak describes the principles behind it. We follow physicians in India and Siberia treating patients for a variety of ailments from paralysis to heart disease, and meet researchers in Israel and Switzerland to see how western clinical studies are testing the effectiveness of Tibetan medicine.
