En route to vacation and a seminar on Risa, Geordi La Forge is captured by the Romulans, who program him though his VISOR to help in an assassination plot against the Klingons. Meanwhile, the Enterprise is assigned to escort Klingon Ambassador Kell to the Kriosian system, where one of the Klingon colonies is fighting for independence. The governor of Krios charges that the Federation is secretly supplying the rebels with weapons.

• The Romulans are trying to break the Klingon-Federation alliance. The Romulans furnished the counterfeit weapons.
  
• Romulan Commander Sela first appears in this episode (hidden in the shadows), but we don't get a good look at her until "Redemption, Part I", and she is not identified by name until "Redemption, Part II". An extra played Sela on screen, and Denise Crosby later provided the voice.
