When Spock is publicly assassinated at a Romulan peace rally, Starfleet and the Federation are unable to search for the criminals responsible without triggering on intergalactic war. It falls to James T Kirk, now retired, to investigate his friend's murder. Given clandestine assistance by Captain Will Riker of the Starship Titan, and accompanied by his good friend Jean-Luc Picard, Kirk travels to Romulus as a civilian, along with his five-year-old child, Joseph. On the Romulan world Remus, Kirk unexpectedly encounters an alluring enemy from his past as Picard and he discover that Spock's apparent murder hides an even deeper mystery, literally reaching back in time to the origin of life on Earth.
Trapped on an alien world on the eve of a Romulan civil war that could drag the entire galaxy into the conflict, Kirk discovers a hidden Reman fortress. There, he learns of the true threat facing the Romulans, and is forced into the heartrending realization that for peace to prevail, he must sacrifice the freedom of his son, whose very blood holds a staggering secret.
