On the day of James T. Kirk's birth, his father dies on his ship in a last stand against a mysterious alien vessel. He was searching for Ambassador Spock, who is a child on Vulcan, disdained by his neighbors for his half-human nature. Twenty years later, Kirk has grown into a young troublemaker. He is inspired by Capt. Christopher Pike to fulfill his potential in Starfleet, even though he annoys his instructors. Suddenly, there is an emergency on Vulcan when the Romulan Nero comes from the future to take revenge on the Federation. The newly commissioned USS Enterprise is crewed with promising cadets like Uhura, Sulu, Chekov and even Kirk himself thanks to Leonard McCoy's medical trickery. Together, this crew will travel to the final frontier where the old legend is altered forever.
