Every year, spectacular seasons transform our planet. These beautiful stand alone films explore the unique opportunities and challenges posed by each season. Spring brings new life, but it's also a dash to wake up and get ahead of everyone else. Summer is a time of long days and glorious abundance. But the living isn't always easy when the temperatures rise. Autumn brings the world's most spectacular transformations.
It's also the last chance to breed, to grow up, to stock up before the cold returns. And during winter - the most magical, dramatic season of all - animals find inventive ways to survive.
