Sweet November

Sara... She had to be remembered by every man she met. So she divided the calendar into twelve men and gave each a month and a key to her apartment. Charlie's month was November because he belonged to Sara as no one ever would again.

Sara Deever, a kooky Brooklyn Heights girl, sublets apartments and paints in her spare time. Each month, Sara selects from her lodgers a new lover - but only on the condition that he will let their affair end when the month expires. When Charlie Blake, a box manufacturer and her lover-of-the-month, falls in love with her, he is unwilling to give her up. Sara insists, even though it is obvious that she too has fallen in love. As the month runs out, Charlie searches desperately for the key to Sara's persistence. What he discovers provides the haunting climax to this love story.
