Nina Sayers is a ballerina in the New York Ballet. She lives with her mother, and her whole live revolves around dancing. There is a new production starting and Nina is determined to get a starring role in Swan Lake. So she sets out to impress the producer/director, Thomas, who believes that she is technically perfect. And if he were just casting the White Swan he tells her that she would be perfect, but she doesn’t have the sex appeal to play the Black Swan. She is too controlled, he wants her to let go.
