This film documents, one of the least-known yet most remarkable pharaohs of ancient Egypt. Psusennes I, who reigned around 1000 BC, was buried in a casket of solid silver and surrounded by treasures which rival those of Tutankhamun; the tomb of Psusennes is the only pharaoh's tomb ever found which hadn't previously been entered by tomb-raiders. His remarkable story has been overlooked partly because the initial discovery was made in 1940, overshadowed by the outbreak of World War II.

An Indonesian legend claims that monkeys can speak but they prefer to stay quiet. Do animals have languages that we don't understand? Is it just a question of getting the right dictionary or is language the one thing that separates humans from the rest of the animal kingdom? Birds sing, lions roar and chimpanzees chatter but do these noises mean anything? This one-hour documentary takes viewers into the wild to listen to nature's noisemakers and meet some of the scientists who spend their days trying to have conversations with animals. From parrots to killer whales we find out who is saying what to whom and explore whether there is such a thing as animal language.

Like us, animals are exposed to parasites, bacteria and viruses – the germs which cause disease. How do they survive these attacks? Recent research and observation have shown that animals use plant and insect substances to treat themselves – not only do they apply things to their skin, they actually treat themselves by feeding on things not normally part of their diets. Capuchin monkeys rub citrus fruit on their fur, caterpillars eat poison hemlock, herbivorous red deer have even been seen chewing the legs off live seabirds. This film takes off around the world to discover how animals use medicine, it questions what notions they have about health and how medical knowledge is passed on from one generation to the next. In doing so, the film also asks what we can learn from animals about medicine.

Man is not the only social animal. At the beginning of 2001, Franz de Waal published his work on a group of chimpanzees in the Arnhem zoo, in the Netherlands. He showed the existence of elaborate and subtle rites which, according to him, revealed a political organization. This fueled the foundation of an argument much debated in today's scientific world. Man would therefore no longer stand as the only "political animal" as defined by Aristotle. Schemes, coalitions, and mediation are all aspects of chimpanzee behavior. Long before man took hold of the political domain, nature had provided other animal species with a whole array of political stratagems, from the most cunning to the most egalitarian: polyergus ants have been practicing slavery for millions of years, hamadryas baboons have a right of veto and deer on the Isle of Rum have established their own democracy. Biologists have even realized that some traits of character used by politicians to fulfill their ambitions (and reach their goals) can be found in other animal species. Domination, alliance-building, seduction and manipulation are forms of intelligence no longer monopolized by man. Barriers continue to fall as discoveries on animal societies throughout the world progress.

Altruism, an act that bestows a benefit on the recipient while conferring a cost to the actor, is one of the central paradoxes of evolution. In the wild, where only the fittest survive, adopting other animals' offspring is not really in line with Darwin's theory of evolution. And yet, amongst bees, dolphins, lions and several primate species, altruism may go as far as adoption. In the case of social insects, parent substitution was a flaw in Darwin's theory of evolution by natural selection: the biologist noticed that non-reproductive insects who adopted and helped young ones, brought a large portion of genetic baggage from their parents. Darwin had to broaden his theory to the family group. For mammals, including men, what advantage is there in the act of adoption? In the years following the adoption, does the adopted individual contribute to the foster parents' survival and vice versa? The controversy at the heart of this documentary continues to be debated in today's scientific world. While raising these different questions, this documentary will study each case separately because each adoption behaviour has evolved independently forming its own pattern, its own benefit and even... its own disadvantages.

Recent discoveries have shown that hundreds of animal species use tools. New Caledonia crows, for instance, use twigs to remove insect larvae from their galleries; sea otters use flat stones to break open urchin shells or earshells; tailor ants weave leaves together with the threads secreted by the specie's larvae. Until recently, it was believed that the human tool was different from the animal tool which is neither transmitted nor accumulated. Several long-term studies on animal populations have proven quite the contrary. The animal tool can be cultural, some chimpanzee populations for instance have their own technical traditions: they crack nuts with stones. Supported by these observations, this comprehensive documentary will be structured around three central questions: how does the tool-using animal transform the world? And by extension the others? And how does the tool transform the animal's behaviour?

This documentary explores YouTube and the revolutionary impact it has made.

In 1981, Ronald Reagan is propelled into the U.S. presidency, but his much-scrutinized administration is shaken to its core a mere 70 days in when an assassin’s bullet pierces his lung. Vivid accounts from newsman Sam Donaldson, on the ground that day, and Dr. David Adelberg, the medical intern who cradled Reagan’s heart in his hands during surgery, describe a country in panic. After a full recovery, and an ensuing upswing in popularity, Reagan’s business mandate leads to a new breed of entrepreneurs, including Steve Jobs, whose “1984” commercial helped launch the Super Bowl commercial phenomenon; Ted Turner, who reinvented the news business with the creation of 24-hour news; and Ben & Jerry, who successfully combined the hippie vibe of the 1960s with the entrepreneurial spirit of the 1980s.
