  • Extraordinary teen John Smith (Pettyfer) is a fugitive on the run from ruthless enemies sent to destroy him. Changing his identity, moving from town to town with his guardian Henri (Olyphant), John is always the new kid with no ties to his past. In the small Ohio town he now calls home, John encounters unexpected, life-changing events-his first love (Agron), powerful new abilities and a connection to the others who share his incredible destiny.

  • High school senior John Smith, who with his father Henri have just moved to the small town of Paradise, Ohio, is outwardly your typical American teenager. However, John, which is just his latest assumed name, in reality is from the planet Lorien. When he was just an infant, he and eight other Lorien infants escaped from Lorien when the planet was overrun by the marauding Mogadorians, who killed all the other Loriens. Each of the nine was assigned a "protector" warrior, John's being Henri. The nine are all on Earth, but each has no idea the whereabouts of the other eight. The Mogadorians are out to find and kill the nine in order, John who is number four. His and Henri's move to Paradise was after John felt that number three was killed, meaning that he will be next. Although John is aware of his heritage, he only knows life on Earth as being his true history, and thus has many of those wants of the American teenager. Their move to Paradise coincides with John beginning to understand that he has special powers, which was why he was one of the chosen nine. Although Henri wants him to stay under the radar, John has a less than an inauspicious introduction to life in Paradise, largely because of his associations with classmates. One is with Sam, who is the oft picked upon boy, largely because his father, who long went missing, had always believed in extraterrestrial life, that belief which he passed onto Sam. The other is Sarah Hart, the first girl to who John has ever been attracted. The issue with Sarah is that she is the ex-girlfriend of Mark James, the football team's quarterback and chief bully who still wants Sarah back despite he having bad mouthed her publicly since their break-up. John's notoriety in combination with the problems of John dealing with the regular issues of teenaged life may make John and Henri easier to find by the Mogadorians, and thus place the lives of all those in Paradise in danger. All the while, Henri continues with his primary other mission which is to help John find the remaining five, who in combination can better battle the Mogadorians.

  • John Smith, tries his best to play the nondescript high school senior who's just moved to a small mid-Western town in Ohio with his single-parent dad, Henri. But maturity ushers in the onset of extraordinary powers that are John's birthright as one of the very few individuals who escaped the genocidal rampage of the Mogadorians, an alien race that destroyed the inhabitants of Lorien, the planet where John was born. A total of eight infants escaped to Earth, each accompanied by a warrior to serve as their guardian and protector. The Mogadorians quest to destroy the last of the Loriens has led them to Earth. Three of their targets have already been eliminated. It becomes John's task to find and join with the remaining members of his race before he becomes victim number four.

  • Aliens and their Guardians are hiding on Earth from intergalactic bounty hunters. They can only be killed in numerical order, and Number Four is next on the list. This is his story.

  • An alien from planet Lorien (Alex Pettyfer) 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 called 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 discover 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 disappear just like that 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 Sarahs 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 make herself invisible 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. They set to find them 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.
