This film begins with a hostile take over of the Federation by a renegade Vulcan. He also takes Klingon and Romulan ambassadors as hostages on Nimbus III, commonly known as a planet of galactic peace. As such, Admiral James T. Kirk and his crew are forced back into action. They take to the skies in the new starship, the Enterprise-A, in hopes of saving the day. But the Vulcan is able to control the crew of the Enterprise, which allows him to put them on a course towards the very center of the galaxy, leading them on a mission of faith, believing that they will find God there.
