The K of D follows the growing "legend" of Charlotte McGraw, as narrated by a pack of teenagers who live near Charlotte on a man-made lake in southwest Ohio. As with all great legends, truth and fiction become inextricably linked in this play. The truth is that Charlotte's brother was hit by a car and died in her arms and that moments before he died he kissed her gently on the lips. The legend is that everything Charlotte kisses from that moment forward also dies. The K of D begins upon the discovery of her new "skill" and tracks the events that transpire when the man who killed her brother returns to town and Charlotte's family attempts to use her new skill to get rid of him.
