Fair Isle is Britain's most remote inhabited island, situated halfway between the Shetland and Orkney Islands. It's an extraordinary place to live. There's no power at night, no pub and it can be cut off for days at any time of the year. Once home to nearly 400 people, today Fair Isle's population is just 55 - a perilously low number on an island where all essential jobs are carried out by the hard-working community, who are doing everything they can to increase their population and ensure the island's survival. This intimate two-part series begins with the arrival of a new couple and follows them as they settle in and adapt to island life, and follows a family whose 11-year-old son has to leave home to board at secondary school on mainland Shetland.
