Having saved the Federation one more time in Star Trek: The Undiscovered Country, Captain James T. Kirk and the crew of the U.S.S. Enterprise have finally gone their separate ways. Spock, McCoy, Sulu, and the others are spread out across the galaxy, pursuing their own individual destinies – until an interstellar crisis touches all their lives.
Bored with retirement, and ill-suited to teaching at Starfleet Academy, Kirk jumps at the chance to help his young nephews colonize an uninhabited planet in a distant corner of the Alpha Quadrant. He even manages to persuade Scotty and Chekov to come along for the ride.
But Kirk soon discovers that the hardy human colonists are not alone on the planet they call Sanctuary. An alien race, of whom little is known, has also established an outpost on Sanctuary – for its own mysterious reasons. Suspicious, Kirk investigates, only to discover a terrifying threat that strikes at the security of the entire Federation.
Bridging the gap between two generations of Star Trek motion pictures, The Last Roundup fills in a missing chapter in Star Trek history – and provides science fiction's greatest heroes with an unforgettable final hurrah.
