Out of money and with little to show for his art school education, John-Calum Macleod takes the ferry back home to the Isle of Harris in the Outer Hebrides to find that little has changed except for him. He returns to the windswept croft and the two pillars of his childhood: his father John, a sheep farmer, tweed weaver, and lay preacher in the local Presbyterian church, and his maternal grandmother Ella, a profanity-loving Glaswegian whose steady warmth helped Cal weather the sudden departure of his mother.

Cal privately wonders if any lonely men might be found on the barren hillsides of home, while John is dismayed by his son’s long hair, strange clothes, and seeming unwillingness to be Saved. But Cal isn't the only one in the croft house who is keeping secrets. As lambing season turns to shearing season, the threads holding together the community together become increasingly frayed, and nothing will remain as it was before.
