Worf gets an unexpected visit from his younger brother Kurn, who arrives on the station drunk and brandishing a knife. Kurn is released into Worf's care. When Kurn wakes in Worf's quarters he confronts Worf about the dishonor Worf has brought upon the House of Mogh after rejecting the Klingon Empire's war with the Cardassian Empire. Worf acknowledges what has happened but would debate it with Kurn. As a result of Worf's choices, his house has been disbanded, its land and ships all seized. Kurn was consequently ejected from the High Council and dishonored. Kurn has lost everything he cared about and has lost all honor and Worf has taken it away without suffering the consequences. Now he wants Worf to give him back his honor the only way he can, by having Worf ritually kill him. Worf begins the ceremony, but Jadzia Dax realizes what Worf is planning when she runs into Odo and finds out that the Klingon who came to see Worf was his brother as well as the incense that he purchased. She and Odo rush to interrupt the ceremony but Kurn has been stabbed, Dax quickly has herself and Kurn beamed to the Infirmary and Dr. Bashir manages to save him. Captain Sisko is furious and forbids that Worf complete the ceremony and reminds both Dax and Worf that he has given them both a lot of leeway with regard to Klingon ritual and says frankly that he has reached the limit of what he will allow.

Worf visits Kurn where Kurn tells Worf that he is not truly Klingon. Kurn points out that despite initiating the ceremony, Worf did not threaten and vigorously fight Dax and Odo to continue the ceremony, nor did he come ready to kill Kurn in the infirmary. Kurn, without an honorable life or death, places himself in Worf's hands. Dax visits Worf to apologize for stopping the ceremony and Worf says that she acted as she felt was right and that that was honorable. Worf asks Dax for advice about what to do next as Worf believes that Kurn will need something to do with his time. At Dax's suggestion, Worf asks Odo for a favor and gets Kurn a position with Odo's Bajoran security force. However Kurn loses his position when he allows himself to be shot without any attempt to defend himself.
