Following the explosive events of "Star Trek: Nemesis" the Romulan Empire is in disarray. When the Vulcan Ambassador Spock is publicly assassinated at a Romulan Peace Rally it falls to James T. Kirk to uncover the truth about the death of his beloved friend.
There are crises enough for James T. Kirk to contend with: a Romulan-Reman civil war, Ambassador Spock assassinated and closer to home, a violent rebellion against him by his son. Then comes a call when he least expects it: one last time, the Federation is asking for his help.
