This thrilling and sweeping Star Trek adventure from William Shatner brings together multiple generations to face an unstoppable enemy in a battle for the existence of all life in the galaxy and beyond.

Following the explosive events of Star Trek Nemesis, the Romulan Star Empire is in disarray, and Ambassador Spock attempts to render aid by launching a last-ditch effort to reunify the Romulans with their distant forebearers, the Vulcans. But when Spock is publicly assassinated at a Romulan peace rally, Starfleet and the Federation are unable to search for the criminals responsible without triggering an intergalactic war.

Thus, it falls to the now retired James T. Kirk to investigate his beloved friend’s murder. Given clandestine assistance by Captain Will Riker and accompanied by his good friend Jean-Luc Picard, Kirk travels to Romulus as a civilian, along with his five-year-old child, Joseph, the cantankerous Doctor McCoy, retired Chief Engineer Montgomery Scott, as well as several members of Picard’s crew. But on Romulus’s sister world, Remus, Kirk unexpectedly encounters an alluring enemy from his past as Picard and he discover Spock’s apparent murder hides an even deeper mystery, literally reaching beyond the limits of the galaxy.

Trapped on a deadly, alien world on the eve of a Romulan civil war that could plunge the galaxy into a civilization-ending conflict, Kirk’s investigation at last brings him to the heart of a staggering conspiracy. Now, he discovers 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 the secret to his startling destiny.
