A teenage fugitive with an incredible secret races to stay one step ahead of the mysterious forces seeking to track and destroy him in this sci-fi action thriller from director D.J. Caruso (Disturbia, Eagle Eye). With three dead and one on the run, the race to find the elusive Number Four begins. Outwardly normal teen John Smith (Alex Pettyfer) never gets too comfortable in the same identity, and along with his guardian, Henri (Timothy Olyphant), he is constantly moving from town to town -- the perpetual new kid in a series of strangely familiar schools. Despite the fact that his nomadic lifestyle has made it difficult to form meaningful connections, John experiences the joy of first love with a beautiful young woman (Dianna Agron) and begins to unlock his full potential after arriving with Henri in a small Ohio town. With each passing day, John gains a stronger grasp on his extraordinary new powers, and his bond to the beings that share his fantastic fate grows stronger.
