Spring arrives in Shetland, bringing with it an influx of wildlife from all over the world. Simon dives in the sea and discovers starfish, dead man's fingers and moon jellyfish. He also gets very close to a seal. Simon follows the heart-rending struggle at a wildlife sanctuary to teach Kirikoo, a damaged baby otter, to use her back legs. And with a little help and hindrance from his two-year-old daughter, Savannah, he sets up a hide and gives her a lesson in birdwatching.
