When district nurse Octavia Berry arrives to start her new job on a remote Scottish island, the last person she expects to see is her estranged husband. With a population of seventy-two and at the mercy of the elements, the island offers the peace and fresh start she longs for— but considerably more complications than she anticipated.
Pastor Ulysses Pine finds the island the perfect spot to assuage the sins of his youth. He spends his days tending many of the island sheep, as well as pastoring his human flock. The arrival of Octavia, the woman he abandoned on their wedding day, turns his ordered life upside down.
As Christmas approaches, Octavia and Ulysses face a collision course with the past, whilst they try to navigate through the present.
