David Attenborough reveals the surprising truth about the cold-blooded lives of reptiles and amphibians. These animals are as dramatic, as colourful and as tender as any other animals.

Follow the path of the sun on its annual cycle, from the Equator, across the northern hemisphere and into the South. Witness a world bursting with life, as spring and summer follow the passage of the sun. Revealed in all their glory are the natural rhythms of life - the urge to breed, to feed and to raise young - all driven by the sun, the moon and the seasons, across the world.
