(click CC for subtitles) 'a-ha' is Norway's only international pop band and their hit 'Take On Me' is still one of the most-played songs of the last millennium. The film follows the band over a period of four years, telling the full story of how three young men followed their impossible dream of becoming Norwegian pop stars. When 'Take On Me' reached number 1 on Billboard in the US in 1985, the dream came true. Or did it?
Almost 35 years after their breakthrough, a-ha still creates magic on stage with their melancholic and timeless music. They tour the world but drive in separate cars and stay in separate hotel rooms. They only meet on stage, doing the one thing they love. The film closely portrays the challenging creative and personal dynamics of a group of three strong individuals who have grown up together, but in different directions. What does success do to friendship? Why are they not capable of creating new music together anymore? This is a story of great music, big ambitions, broken friendship--and maybe forgiveness.

Sir David Attenborough chooses his favorite recordings from the natural world --from the song of the largest lemur to the song of the humpback whale to the song of the lyrebird-- that have revolutionized our understanding of song. The science of song had been transformed by Charles Darwin’s theory of sexual selection: singing is dangerous as it reveals the singer’s location to predators, but it also offers the male a huge reward, the chance to attract a female and pass on genes to the next generation. Today, new science in the field of birdsong is transforming those long-held ideas.
Scientists are discovering that, in fact, in the majority of all songbird species, females sing - and it is only now they are being properly heard. Through this revelation and others, we can understand that animal songs are marvellous examples of the spectacular survival strategies that species have developed.
