Fair Isle is Britain's most remote inhabited island, situated halfway between the Shetland and Orkney Islands. Life here is at the mercy of the weather. Once home to nearly 400 people, today there are just 57. Fair Isle must boost its population if it is to survive. Filmed over a critical year, this intimate series captures the community as they launch their Development Plan with an aim of bringing new families to the isle and bolstering the fragile economy. This final episode continues to follow 11-year-old Ythan and his family as they learn to deal with his homesickness, and reveals if Fair Isle's newest inhabitants, Shaun and Rachel, have survived their first winter and decided to stay on.
