I Am Number Four is a 2011 American science fiction action film directed by D. J. Caruso and starring Alex Pettyfer, Timothy Olyphant, Teresa Palmer, Dianna Agron, and Callan McAuliffe.

John is protected by a guardian (who is called Cêpan), Henri, and has developed powers, including enhanced strength, speed and agility.

Knowing this, he and Henri move from a beachside bungalow in Florida to an old farm in Paradise, Ohio, where John befriends conspiracy theorist Sam Goode and a Beagle which he names Bernie Kosar.

The next day, Mark's father, the local sheriff, interrogates Henri on John's whereabouts when his son and his friends were attacked.

Henri dies, while John and Sam escape with some Lorien artifacts, including a blue rock that acts as a tracking device for other Garde.

While Sam searches for it, John tries to say goodbye to Sarah at a party, only to discover that the Mogadorians have framed him and Henri for the murders of the conspiracy theorists.

They set off to find the others so they can protect Earth from the Mogadorians, leaving Sarah and a repentant Mark, who lies to his father about John's whereabouts.
