The BBC's Natural History Archive celebrates the extraordinary nature of the four magnificent seasons on Planet Earth, and how animals and plants rise to the new challenges they bring. In each episode, we visit a different season, each with its own magical and dramatic personality, and reveal how different animal characters must find their own extraordinary ways to make it through.

Narrated by Andrew Scott.
