Star Trek (film)/Summary/Act One

Approximately ten years later, around the early to mid-2240s, a young boy is seen racing down the road in an antique Corvette across the open Iowa landscape, blasting 20th century . Soon, a policeman on a flying motorbike chases him, ordering the boy to stop the car. Evading the officer, the boy heads for a quarry and jumps out of the car, moments before it speeds over the edge and crashes on the canyon floor below. The policeman apprehends the boy, who defiantly identifies himself as "". 
Around the same time on , a young is being tormented by his peers about his mixed heritage. The boys call his father a traitor for marrying a Human "whore". The three have previously failed 34 times to invoke an emotional response in Spock, but this time they take it too far and Spock knocks one of the older boys into a skill dome and beats him in an emotional rage. 
He is later gently admonished by his father, , who is disappointed at his son's lack of emotional control. Spock suggests that his father wants him to be fully Vulcan, and yet Sarek married a Human woman. Sarek coldly replies that it was the logical choice, as his duties as ambassador to Earth required him to understand and observe Human behavior. Sarek then tells his son, "Spock, you are fully capable of deciding your own destiny. The question you face is: which path will you choose? This is something only you can decide."
Many years later, Spock is conflicted about whether to participate in the kolinahr, the Vulcan ritual aimed at purging all vestigial emotions. He talks to his mother, , who tells him that she will always be proud of him, no matter what he decides. 
Later, Spock stands before a committee on Vulcan. The committee informs him of his acceptance into the Vulcan Science Academy and commends his accomplishments despite his "disadvantage" of being half-Human. In response to yet another underhanded insult to his heritage, Spock declines the offer of admission, stating that he has decided to enter Starfleet Academy instead. The committee expresses shock, as the offer of admission to the Vulcan Science Academy is one that no Vulcan has ever turned down – to which Spock replies that, as he isn't a real Vulcan, that statement is still accurate. Spock thanks the council and with a tinge of anger in his voice, tells the committee to "live long and prosper."
In 2255, in a bar in Iowa, a young Academy cadet named meets up with some friends, and while ordering drinks, a brash and intoxicated James Kirk introduces himself to her and offers to buy her a drink. His attempts at flirting with her are unsuccessful, however, and the situation escalates when three Starfleet recruits led by intervene and end up in a fight during which Kirk is badly beaten. Fortunately, Captain steps in and ends the fight, ordering all cadets inside the bar to step outside.
Pike, who is very familiar with Kirk's tragic past and the accomplishment of his father, having written his Academy dissertation about the Kelvin, sits down with him, trying to talk some sense into the rebellious young man by trying to persuade him to join Starfleet. Pike firmly believes that with his aptitude, Kirk can do more with himself than get into bar fights and be "the only genius-level repeat offender in the Midwest." Kirk doesn't want to hear it and laughs at the idea of joining Starfleet. Pike ends the conversation with a reminder that Kirk's father saved eight hundred lives in the course of just twelve minutes of command and challenges Kirk to do better.
Early the next day, Kirk heads to Riverside Shipyard on his motorcycle, where the is under construction. Pike is surprised to see Kirk turn up to join the new recruits. Before boarding the shuttle Bardeen, Kirk gives away his motorcycle and smugly tells Pike that he'll graduate in three years instead of four. On the recruit shuttle, he meets – a recently divorced, disgruntled recruit who dismisses Starfleet technology with smug pessimism. The two share a drink as the shuttlecraft leaves for the Academy in San Francisco.
Three years later, the Narada is waiting at an unknown part of space. Nero is called to the bridge by Ayel. Suddenly, a black hole temporal disturbance appears and a small starship flies out of the anomaly. Nero recognizes and welcomes the appearance of Ambassador Spock, and orders the ship to be captured.
Meanwhile, at Starfleet Academy, Kirk is telling McCoy that he is taking the Kobayashi Maru test again the next day, and is certain he will pass it. McCoy is shocked at Kirk's confidence, as no one has ever passed the test, much less repeated it. However, Kirk is convinced that he will nail it and leaves to "study", which for him means an assignation with an Orion cadet named in her dorm room. Suddenly, Gaila's roommate enters and Kirk is forced to hide under the bed. He is mortified to find that the roommate is Uhura. Undressing down to her underwear, she describes to Gaila decoding Klingon transmissions about 47 battle cruisers destroyed near a prison planet. She hears him breathing however, and eventually discovers him and angrily kicks him out.
The next day, Kirk, McCoy, Uhura, and a few other Starfleet recruits are in the Kobayashi Maru simulation test on Kirk's third attempt. Kirk takes a comically casual approach to the test, including eating an apple. Everything goes as planned when, unexpectedly, the power systems momentarily fail, and then the attacking Klingon ships' shields go down and the ships are promptly destroyed. From above the simulator room, a technician asks how Kirk was able to beat this test. Spock, who is in the observation room, is equally puzzled. 
During an official inquiry, the Starfleet Academy brass, namely Admiral Richard Barnett, informs Kirk that they have received evidence that Kirk entered a subroutine into the computer making it possible for him to win in the simulation, and accuse him of cheating. While Kirk faces his accuser, Spock, and tries to defend himself, the is suddenly interrupted when the committee is informed that the Federation has received a distress call from Vulcan. With the primary fleet occupied in the Laurentian system, Starfleet is forced to commission the Academy cadets and dispatch ships immediately to begin a rescue mission.
