J.J. Abrams is very good at keeping his plots a secret, and only revealing information when he chooses.  He's done a terrific job keeping his cards close to the vest for Star Trek Into Darkness, but as we count down to the reveal of the first trailer and first nine minutes of the movie (the latter being shown in front of The Hobbit: An Unexpected Journey in IMAX 3D), the official synopsis has been announced.

Hit the jump for the synopsis.  The film stars Chris Pine, Zachary Quinto, Karl Urban, Anton Yelchin, Zoe Saldana, John Cho, Simon Pegg, Alice Eve, Peter Weller, Noel Clarke, and Benedict Cumberbatch.  Star Trek Into Darkness opens in 3D and IMAX 3D on May 17, 2013.

Here's the official synopsis for Star Trek Into Darkness:

In Summer 2013, pioneering director J.J. Abrams will deliver an explosive action thriller that takes "Star Trek Into Darkness."

When the crew of the Enterprise is called back home, they find an unstoppable force of terror from within their own organization has detonated the fleet and everything it stands for, leaving our world in a state of crisis.

With a personal score to settle, Captain Kirk leads a manhunt to a war-zone world to capture a one man weapon of mass destruction.

As our heroes are propelled into an epic chess game of life and death, love will be challenged, friendships will be torn apart, and sacrifices must be made for the only family Kirk has left: his crew.

Reading the synopsis, it sounds like a damn good picture.  We still don't know the name of the villain, but we now know that Captain Kirk is out for revenge and on a mission to track down a "one man weapon of mass destruction."  The synopsis also mentions that there's "an unstoppable force of terror within their own organization", so I'm left to wonder if that's why Cumberbatch's character has the faint outline of a Starfleet insignia on his chest in these set photos.
