Fair Isle: Living On The Edge - 2016 - 6/10

Breeders needed! Tiny island in northern Britain is looking for newcomers.
Current population is 57, not counting the sheep.
Power goes off at nights. Owing to storms, sometimes the island is cut off for weeks.
Just to keep the island going, inhabitants must do 3 - 4 - 5 jobs.
Isolation? Plenty. Awe inspiring nature? This is the place.
Mind you, during summer scenes many still wore jackets. Winter? Lordy.
Two part series of inhabitants fighting valiantly to maintain their community.
