Consisting of a single shot, Spiders on a Web is one of the earliest British examples of close-up natural history photography. Made by one of the pioneers of the British film industry, G.A. Smith, this short film details spiders trapped in an enclosure, and despite the title, does not actually feature a web.

In Over the Cattle Grid you follow to Robert, Rinke and Ytzen, who spend every day in the woods between the villages of Odoorn and Exloo. Ytzen and Rinke because they live in the middle of the woods, Robert because he cycles through the woods every day to get to work. Behind the grid time seems to pass in a different way. Or as Ytzen says "there is no time, there is just being". They also see things they have never seen before, such as trees that lose their leaves in September and plants that want to start growing in the middle of winter. You will also see Wietse de Haan and Evert Prummel, they build instruments from dead trees. All the music you hear in the film was played on these tree instruments and recorded in the forest. Okki herself also occasionally passes by. She has been coming to this piece of forest all her life, which is a kilometer from the house where she grew up. Not only has she known the forest, but also Robert, Ytzen and Rinke for most of her life.

An examination of the extinction threat faced by frogs, which have hopped on Earth for some 250 million years and are a crucial cog in the ecosystem. Scientists believe they've pinpointed a cause for the loss of many of the amphibians: the chytrid fungus, which flourishes in high altitudes. Unfortunately, they don't know how to combat it. Included: an isolated forest in Panama that has yet to be touched by the fungus, thus enabling frogs to live and thrive as they have for eons.

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.
