Dan Elliot is a documentary filmmaker who uses his looks and charm to persuade his subjects to reveal secrets. When their paths cross, Dan becomes her willing pupil, eager to obey and hungry for experience. And Jo assumes the role of his guide, providing punishment, pleasure and entrance into a world of extreme submission.
