I Am Number Four

John Smith (Alex Pettyfer) is an alien from planet Lorien who was sent to Earth as a child alongside eight others to escape an invading race, the Mogadorians, which destroyed their home planet. He is protected by a Warrior/Guardian, Henri (Timothy Olyphant), and has developed "legacies" due to his extraterrestrial nature, such as enhanced strength, speed and agility, telekinesis, and the power to generate light from his hands. The Mogadorians, led by the Commander (Kevin Durand) eventually learn about the nine children and come to Earth in search of them. These Loriens can only be killed in a particular sequence, with three of them having already been slain. John is Number Four. Knowing this, he and Henri move from Florida to Paradise, Ohio, where John befriends conspiracy theorist Sam Goode (Callan McAuliffe), a dog named Bernie Kosar, and falls in love with amateur photographer Sarah Hart (Dianna Agron), whose ex-boyfriend, school athlete Mark James (Jake Abel) is a bully who often torments both John and Sam. During the spring carnival, Mark and his friends try to capture John and Sarah, whom they believe are in a relationship, and follow them into the woods, where they attempt to beat John up. However, he uses his legacies to fend them off and rescue Sarah. Sam witnesses the events, and John tells him his true origin. Shortly thereafter, Mark's father, the local sheriff, interrogates Henri on John's whereabouts when his son and his friends were attacked, and notices that he has a high-tech surveillance system. Henri tells John that too many people are suspicious of them, in addition to John's random displays of power, caused by his difficulty in controlling them, and that they must leave. However, John tells him he doesn't want to because he's in love with Sarah. The Mogadorians start searching for John. Another alien from Lorien, Number Six (Teresa Palmer), decided to go after the Mogadorians instead of running away from them after her Guardian was murdered. The Mogadorians eventually locate John and manipulate two conspiracy theorists into capturing Henri. When John and Sam go to rescue him, they are attacked but manage to fend Mogadorians off. However, Henri is mortally wounded and dies after John and Sam escape with some Lorien artifacts, including a blue rock that acts as a tracking device to locate other Loriens. Sam's father, a conspiracy theorist who disappeared while hunting aliens in Mexico, has another. 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, as well as being terrorists due to their cutting-edge technology. Mark sees John and calls his father, who corners John and Sarah. He saves her from a fall, revealing his powers in the process, and they escape to their high school......
