Spock, a boy born in Vulcan in 2230, his mother is a school teacher on the earth. Spock's mother received all the traditional education on the earth from childhood, which made Spock's mother's family education extremely strict. His father, Shaq, was a diplomat of Vulcan. On Vulcan, the culture is very different from the earth. Because of this, since Spock was born, he has been struggling between the serious Vulcan logic education and his human feelings, trying to reconcile these two parts, which have been tormenting him for most of his life.

Time flies. When he grows up, Spock decides to pretend to be an earthman. He entered the military academy, determined to become the first Vulcan officer on the Federation starship.

Kirk was suspended for cheating in college, and his good friend "old bones" tried to put him on the Enterprise. Enterprise found a thunderstorm-like phenomenon, and a large number of spacecraft passed by and were destroyed by Nero's spacecraft. On the ship, Kirk and Spock clashed. Kirk was thrown on a planet and accidentally met the old Spock. Old Spock told him why. When Romulus was about to be swallowed up by a black hole, Spock went to help on behalf of the Vulcan people. The result is too late. The last romulan starship "Narada" and Captain Nero wanted revenge and destroyed Vulcan with red substance from Spock "Jellyfish".

Young Spock crashed Narada into a jellyfish, and Kirk became the captain of the Enterprise.
