A Woman's Decision (Polish: Bilans kwartalny, also known as The Quarterly Balance) is a 1975 Polish drama film written and directed by Krzysztof Zanussi.

It is a movie about a woman stuck in an unhappy marriage, with neglectful husband who is distant and unable to make her happy. So she spends her life in limbo of waiting for happiness that is not coming. Eventually after many years of neglect, she feels in herself a need to change her life for the better. Soon she meets someone else, a new guy who can make her feel happy and loved,as she deserves. And then she needs to make a choice - will she stay with her husband out of sense of duty and because she is tired to try to love again someone new, or will she leave her unhappy marriage once for all. And she makes a wrong one - by choosing to stay. In melanholic, unhappy marriage, for the sake of duty.

So this movie is a psychological analysis of female character who wastes her life in waiting. For happiness in marriage that can not give her that. Instead of grabbing her happiness with someone new, who could really make her happy. As said above the movie is Polish.

The music in the movie is done by Wojciech Kilar, Polish film music composer, who is most famous for composing soundtrack for the movie Bram Stoker's Dracula.
