Adapted by multi-award-winning writer and director Andrew Haigh, this is a thrilling tale of struggle and survival. 1859, Patrick Sumner joins The Volunteer as a ship's surgeon, hoping to lose himself in the tough physicality of an Arctic whaling trip. But the ferocity of the elements is matched by the violence of his crew mates, with Dray, a harpooner, a distinctly brutal force of nature. As the true purpose of the expedition becomes clear, confrontation between the two men erupts taking them on a journey far from solid ground and way beyond the safe moorings of civilisation.
