Stranded on a small island in the North Atlantic a British sailor fights for survival. With a broken leg and having only the aid of his dog and his knife he must find a way to stay alive and hope for rescue before winter sets in.All the while a vengeful creature haunts his every move. She is one of the sea-spawn and seems dead set on doing her part in the ongoing feud between land-dwellers and sea-folk. She is enchanting but the sailor knows he must kill her or lose his own life-or perhaps his heart.
