Strong performances and eye-catching location photography lift this uneven Hebridean drama, recut since its Edinburgh film festival premiere last year. Returning to the island from which she takes her name, Iona (Ruth Negga) and young son Billy (Ben Gallacher) awaken sleeping resentments in an incestuously tight-knit religious community. Thoughts of damnation and the suggestion of miracles sit side by side, hinting at a bigger picture that never quite comes into focus in this flawed but atmospheric work from Shell writer-director Scott Graham.
