The Starship USS Okinawa has suddenly gone silent whilst en route to Starbase Frontier. The Okinawa was tasked with ferrying supplies and cargo to the starbase from the Federation. The last report was that the ship was under attack and has then fallen silent.

Captain Izumi decides to go locate the Okinawa. What she finds is disturbing. The Okinawa was destroyed by Klingon weapon's fire. An old house of the Klingon Empire reappears, and announces that they will blockade any Federation or Klingon ship attempting to reach Starbase Frontier until their honour and place on the High Council can be restored.
