Three elderly Klingons whose days of glory passed into history and legend with the conclusion of Federation-Klingon hostilities have arrived at DS9 in search of their old friend Curzon Dax. Decades ago, after the three Klingons led a victorious assault on a ruthless enemy, their first sons were murdered in an act of revenge. The bereaved fathers made a pact, along with their mutual friend Dax, to avenge their sons' deaths. After years of searching, the murderer has been found - and they wonder if Jadzia Dax will still honor an oath of vengeance made by Curzon Dax.
