After saving Earth from the threat of V'Ger, James T. Kirk is called again to the final frontier with the mission to lead a valiant group of settlers to a distant world and explore the diverse mysteries and dangers of a strange new world in the Star Trek universe.

Far from the Federation, a newly discovered M-class world has been eyed as a potential home by a group of hardy and determined colonists. Starfleet can spare only one starship to escort the would-be settlers on their perilous voyage, and that ship is none other than the legendary Starship Enterprise, commanded by the most well-known captain in the quadrant. Now Kirk finds himself responsible for the lives of 30,000 men, women, and children-a task that grows all the more difficult when the expedition is caught in the middle of an ancient feud between two dangerous alien races.
