The group claims they are freedom fighters from the future working to save the Federation from the Consilium—a group of corrupt power-seekers. But when the Nautilus crew members suddenly seize control of the U.S.S. Enterprise, and a Starship from the future arrives to arrest the renegades, Kirk must separate his true allies from those who wish to destroy the Federation.
