- Kelvin attacked first, and somehow damages Narada, perhaps destroying itself. George Kirk is killed, but Pike was there and survives.
- Vulcan is attacked years later, and Kirk recognizes this, so Pike raises the shields just in time, leading to the skydive to stop the drilling platform.
- After the failed attack on Vulcan, Nero takes the Narada to Earth, and this attack becomes the basis of the movie's finale.
- Between the Vulcan and Earth attack, we get scenes that shed light on the Narada, older Spock makes an appearance, and other events occur that set the stage for our crew as we know them to form in time for the Finale.
- Between the Kelvin battle and the Vulcan attack, we meet many of our crew at the Academy, and develop the characters, friendships and situations from growing up in Iowa, the bar fight that leads Kirk to the Academy, as well as McCoy and the famous cheating on the Kobayashi Maru which leads to him not being given his shirt and getting McCoy to sneak him ontho the Enterprise when the Vulcan emergency occurs.
So in summary, this is how I think the film may play out:
- Kelvin is attacked by Narada, is destroyed and George Kirk is killed. This is witnessed by Christopher Pike, possibly a lieutenant. Narada is damaged in some way, and Nero is taken out of action for about 18-25 years.
- James Kirk is born, establishing that the Narada failed to kill him by killing his father.
- Spock and Kirk are shown growing up on their respective homeworlds, establishing their backgrounds and certain important character traits (Kirk destroying the car, Spock bullied for not being fully Vulcan).
- Kirk gets into the barfight, where Pike lectures him, and he then goes off to the Academy, where he meets McCoy on the shuttle.
- Spock argues with his father and the Vulcan council about entry into Starfleet's scientific programme instead of following his father into diplomacy.
- Kirk cheats in the Kobayashi Maru test, and engages in other Academy activities. He learns things about discipline, and displays a knack for leadership.
- Kirk and his shipmates graduate, but he does not get his shirt due to the cheating. There is a big rush due to an emergency on Vulcan, and McCoy finds a loophole to get Kirk on board (fake virus).
- Kirk recognises the description of what is happening to being the same as the Kelvin's encounter with Narada, and manages to warn Captain Pike at the last second. Shields go up, and a battle ensues. Spacediving action sequence with Narada drill occurs here.
- Due to deaths and incapacitations, the characters we know gradually fill in the positions we know (Uhura to Communications etc.)
- Something happens in this battle which leads to Pike being taken out of action, and Spock given command. Kirk is thrown off the ship to an Ice Planet due to some conflict with Spock.
- While on the Ice Planet, Kirk faces the creature seen in the trailer, then meets Older Spock, who introduced him to Scotty, who uses a special technique to get Kirk and Scotty to the Enterprise.
- Kirk then gets command of the Enterprise by showing Spock to be emotionally unstable.
- Scotty ends up taking on Engineering, since the Chief Engineer is killed.
- The Enterprise then goes after Narada, and tracks it to Earth for the Finale. Lots of action here !!!
- Once the Narada is destroyed, along with Nero, we are left with Kirk and crew in their legendary positions on the Bridge.
