On the day of James Kirk(Chris Pine)'s birth, his father dies on his ship in a last stand against a mysterious alien vessel. He was looking for Ambassador Spock(Zachary Quinto), who is a child on Vulcan at that time, disdained by his neighbors for his half-human nature. Twenty-five years later, Kirk has grown into a young troublemaker inspired by Captain Christopher Pike(Bruce Greenwood) to fulfill his potential in Starfleet even as he annoys his instructors like young Commander Spock. Suddenly, there is an emergency at Vulcan and the newly commissioned USS Enterprise is crewed with promising cadets like Nyota Uhura, Hikaru Sulu, Pavel Chekov and even Kirk himself thanks to Leonard McCoy's medical trickery. Together, this crew will have an adventure in the final frontier where the old legend is altered forever even as the new version of it is just beginning.
