-Well, Enterprise on her Five Year Mission, encounters strange black cloud.
-Strange black cloud is not a cloud at all but thousends of small dart ships.
-Dart ships attack Enterprise, cut her in half, leaving the discusssegment tumbling down the planet.
-Crew leaving the ship with escape pods, Kirk and the others are the last ones, getting somehow seperated from the others.
-Hot Alien Warrior Chick, sees the Ship crashing and propably Kirks Escape Pod, thinking, Yay, finally some hot Alien Warrior guy.
-Crew are held prisoners by bad guy miners.
-Kirk encounters Hot Alien Warrior Chick. Insert background explenation of the bad guys here. She leads him to her own super secret crash landed Starship and they start to work together to reach the rest of the crew and to escape the planet, somehow preventing the bad guys, from... whatever the bad guys are planning to do. Bad Guy stuff perhaps.
Also, there's a Starfleet outpost under attack. Maybe at the beginning. Insert lot's of explosions and cool one-liners and you have it.
More or less.
