Watch on Soap2day. On a remote island in the Canadian Arctic, a pair of white gyrfalcons and a pack of Arctic wolves are struggling to raise their young. As the falcons' eggs hatch, the parents must find enough Arctic hares to feed them. The wolf pack are raising their cubs in a hillside den. The film records behaviour that has never been seen by scientists, let alone filmed. It is scored by the BBC's New TV Composers Scheme winner Anne Nikitin.
