This is the story of Kor, a Klingon legend, who is suffering from dementia after a violent career. In his younger days he was a reckless, unpopular man. Now he lives in the past but wants a chance to die with dignity. Worf gets him on board a ship on a very dangerous mission, but the Captain despises him. What transpires is a very formulaic plot which I figured out half way through. Nothing much new.
