Housewife Rosemary Edmonds leaves her family to take up residence in a remote cottage on the Otago coastline so that she can conduct a photographic essay on the yellow-eyed penguin. No sooner has she moved in than she becomes the victim of a series of increasingly more malevolent attacks from an unknown assailant.
