Plot summary
Kor (John Colicos), a revered Klingon warrior, is in Quark's bar telling stories of past battles to his friend Lieutenant Commander Jadzia Dax (Terry Farrell). She introduces Kor to her colleague Lieutenant Commander Worf (Michael Dorn). He explains that he is on a quest to find the legendary Sword of Kahless, the founder of the Klingon Empire; he has come into possession of a shroud which he believes once held the Sword. When he returns to his quarters, Kor is attacked by a Lethean who reads his thoughts in order to find out about the Sword. Jadzia verifies the authenticity of the shroud, and the next morning she, Kor, and Worf depart for the Gamma Quadrant to search for the Sword on the planet where the shroud was found.
On the planet, they discover a secret chamber in an underground vault containing the Sword. They are attacked by Toral (Rick Pasqualone), son of Duras, who hired the Lethean and wants the Sword for the prestige of finding it. Kor, Worf and Jadzia fight past Toral and his men and after finding that they cannot transport back to their ship, they head into the adjoining cave system in order to try to escape Toral. As they travel through the caves, the Klingons are affected by the prestige of the Sword: Kor begins to talk about how it would allow him to overthrow Chancellor Gowron and Emperor Kahless II; but Worf believes that he should be the one to lead their people. Suddenly, Kor slips down the side of a cliff but refuses to let go of the Sword. Worf grabs the other end of the Sword, and tries to convince Kor to let go.
Dax helps Worf save Kor, and afterwards takes possession of the Sword because she thinks the two Klingons cannot be trusted with it. The three make camp and Dax tries to sleep, but is awakened by an argument between Kor and Worf. The fight between them stops momentarily when Toral and his men arrive. After Toral is subdued, Kor and Worf again attack each other. Jadzia stuns them both with her phaser and then forces Toral to enable the three to return to their ship. After they depart the planet, Kor and Worf realize that if the Sword divided two men as honorable as they, it would do the same to the Klingon Empire, so they beam it into space, leaving it to drift until the Klingon Empire is ready for it.
