Time in the galaxy has stopped working in its regular course. That can mean only one matter — the Guardian of Forever can be malfunctioning. To save lots of the universe, Starfleet Order reunites three of its most famous figures — Admiral Wayne T. Kirk, Spock of Vulcan, and Dr. Leonard McCoy — and transmits them on the desperate mission to contact the Guardian, a trip that ultimately requires them 5,000 years into the past. They must find Spock’s child Zar once more, and provide him back to their time for you to telepathically talk to the Guardian.

But Zar is enmeshed in issues of his personal, and quickly Kirk, Spock, and McCoy find themselves in a desperate struggle to save both his and their world.
