Lake Tanganyika is an 'Ocean' in Africa. Millions of years ago it was colonized by a little fish called 'Cichlid'. Otters, crocodiles, cobras and cormorants all hunt the fish in clear water. How the Cichlid survived and evolved is an incredible story for, millions of years later, there are over 200 new species - all found only in Lake Tanganyika. Incredibly, they have evolved to look like coral reef fish. There are cichlid equivalents of tuna, snapper, gobies and goatfish. They have evolved bizarre methods of breeding with mouth-incubation, lekking and, unique amongst fish, there is even a cuckoo. Despite all their specialization over millions of years, if an opportunity presents itself, the little fish can behave like their unspecialized ancestor. In the climax of the film, they bang together to feast on a hatch of sardine fry. This is the story of how one little fish has conquered a lake.

This is the story of sound. Everything in the universe produces a unique acoustic signature called a soundscape. From Arctic ice sheets, to viruses, from planets to human beings. Sound is part of our culture, our heritage and an often overlooked part of all ecosystems on Earth. It is the music of the living world, but as we lose natural habitats all across the globe, we also lose its soundscapes. This film centers around the life work of Bernie Krause, a legend in the world of acoustics and soundscape ecology. To date, Bernie has recorded over 1200 individual habitats among his collection of over 50,000 individual recordings (his collection is now the largest collection of wilderness sounds in the world that spans decades of time).

On the African plains, where only the strong survive, one big cat rules supreme. This is life in the raw: savage, beautiful and unforgettable. During the eight years that Jurgen Jozefowicz filmed a pride of lions in South Africa's Kruger National Park, he won the trust of the dominant male and, astonishingly, was accepted into the pride. This is his story. How does it feel to live amidst a group of the most feared predators on the African continent as they fight to survive in a harsh, unforgiving world? Jurgen's film shows what it's like and is the result of his remarkable adventures. Jurgen is one of the world's premier wildlife photographers. His story of his life with these lions is one that spans a period of political struggles, disease and drought, showing the highs and the lows of life in the lion pride.

Four top predators are compared, each champion in a type of environment, with key adaptations. On the ground, the cheetah outruns prey (approached in masterly stealth) and enemies. In the air, the peregrine falcon is a flight and diving machine. In sweet water, the Nile crocodile survives since the Dino age, without natural enemies, with several amazing metabolism stunts. Lurking under water, it snaps blindly at migrating wildebeest, then waits underground. In the oceans, the equally ancient shark, notably the great white, migrates seasonally to find abundant prey, such as young seals around South Africa.
