Plot

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 superpowers due to his extraterrestrial nature, such as enhanced strength, speed and agility, telekinesis, resistance to fire and heat, and the power to generate light from his hands.

The Mogadorians, led by the Commander (Kevin Durand) eventually learn about the nine toddlers 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 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 powers 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 can’t 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.

Meanwhile, The Commander also arrives at Paradise, blocking the exits with trucks. He is confronted by Mark and his father, and, after injuring the latter, he forces the former to show him where John is hiding, Mark then takes him to the school, which he knows is Sarah’s hideout.

There, John, Sarah, and Sam are attacked by the Commander and his soldiers, who have brought two giant monsters to hunt the trio. They are saved by Number Six and John’s "dog," Bernie Kosar, who reveals his true form as a good Chimera, which can shapeshift, and was sent by his parents to protect him. Bernie Kosar eventually shapeshifts back to a beagle with a very wounded paw. John and Number Six, who can teleport and block energy-based attacks, fight the Mogadorians. They eventually defeat them all, including the Commander, whose energy grenades are overheated by John and explode, destroying his body.

On the following day, John, Number Six, Sam, and Bernie Kosar, the shapeshifting Chimera, unite their blue rocks and discover the location of the other four surviving Loriens. John decides to let Sam come with them with hopes of finding Sam's father. They set to find the others and rally them together to protect Earth from the Mogadorians, leaving Sarah and a repentant Mark, who has redeemed himself by lying to his father about John’s whereabouts and returning to John a box belonging to his father. John, Number Six, and Sam leave Paradise to look for the other Loriens.

The film ends as John narrates that Paradise is the first town he left without Henri, but it's also the first one where he has a reason to come back to.
