Worf is excited that his son Alexander has reached the age for the First Rite of Ascension, a ceremony in which a young Klingon declares his intention to become a warrior. However, he is shocked and disappointed to learn that Alexander has no intention of becoming a warrior. At the festival of Kot'baval, they are attacked by three Klingon assailants. A strange Klingon appears and after a brief struggle, the remaining assailants flee. The stranger calls himself K'mtar, a close friend of Worf's family who has been sent to protect them. Markings on a dagger left at the scene indicate that the would-be assassins were sent by the sisters of Duras.

• This episode (and the DS9 episode "Past Prologue") set up Lursa and B'Etor's appearance in Star Trek: Generations.
  
• Deep Space Nine's Quark makes a guest appearance via the viewscreen.
  
• K'mtar reveals that he is Alexander, and has come from the future. K'mtar explains that he grew up to be a diplomat instead of a warrior, and Worf was murdered 40 years later. He decided to transport back in time and either change Alexander's ways or kill him.
  
• This is the last time we see Alexander until the DS9 6th season episode "Sons and Daughters", where he appears as a teenager. Worf apparently sends Alexander back to Earth to live with his grandparents sometime between this episode and Star Trek: Generations.
