This film follows the struggles of a doomed couple.What happens when a woman can no longer prove intimately useful to herself or her husband? Does this make her less of a woman? Knowing--better yet, understanding--that she can no longer fulfill the most important and most precious aspect in her relationship; although it deeply pains her, she sacrifices and encourages her husband to seek the comfort of another woman.
