Worf's brother Kurn arrives unexpectedly and explains that since Worf sided with the Federation against the Klingon Empire, Kurn and his family have become outcasts on the homeworld. Having lost everything, the only way for Kurn to regain his honor is through the Mauk-to'Vor, a death ritual which only Worf can perform. Reluctantly agreeing, Worf fatally stabs Kurn, but Dax and Odo burst in and transport Kurn to the Infirmary. When Kurn survives, Worf must struggle to find an honorable life for his brother.
