A diplomat's perfect life shatters when he learns his young son is the prophesied Antichrist, meant to bring about evil.
In Rome, American diplomat Robert Thorn goes to the hospital where his wife, Katherine, is giving birth. He learns their newborn son has died. Father Spiletto, a priest, offers Robert another baby boy born at the same moment, whose mother died. Spiletto suggests Robert swap the babies, letting Katherine believe the orphan is their own and sparing her grief. Robert agrees, naming the child Damien. Katherine does not know about the deception. The family soon moves to London, where Robert is appointed Ambassador.
Damien Thorn's fifth birthday party is held at the Thorn estate in London. As guests gather, the nanny, Holly, suddenly hangs herself from the roof railing. She proclaims 'Look at me, Damien! It's all for you!' before she dies. Katherine, who is pregnant again, is traumatized. Soon after, a new nanny, Mrs. Baylock, arrives unannounced. She quickly controls Damien. Strange events continue, including animals acting aggressively when Damien is near, especially at a zoo where monkeys attack the family car.
Father Brennan, a disheveled priest, repeatedly tries to contact Robert Thorn, saying he has information about Damien. He confronts Robert in his office, revealing that Damien is not human but the son of Satan, meant to bring about the end of the world. Brennan warns Robert that Katherine's unborn child threatens Damien and will not survive. Robert dismisses him as mad. Later, Brennan dies after being impaled by a lightning rod that falls from a church steeple during a sudden storm, just as he was trying to warn Robert again.
Katherine Thorn becomes disturbed by Damien's behavior and the strange events around him. She starts to believe Father Brennan's warnings. She tells Robert her fears about Damien. During a park visit, Damien has a violent tantrum when he cannot go to a church. Later, while playing indoors, Damien deliberately knocks Katherine off a railing, causing her to fall from a height. She suffers severe injuries and a miscarriage. Her trust in Damien is gone, and she says he is evil.
Keith Jennings, a photojournalist at Damien's birthday, notices a black mark resembling a spear through the nanny's neck in his photographs, and similar marks on other victims. He investigates the deaths around the Thorn family. He contacts Robert, showing him the photos and sharing his suspicions. Together, they connect the events to Father Brennan's warnings. Jennings discovers an ancient biblical prophecy in the Book of Revelation about the Antichrist, identifying the 'mark of the Beast' as 666, and realizing its connection to Damien.
Following clues from Father Brennan, Robert and Jennings go to Rome to investigate Damien's origins. They visit the hospital where Damien was supposedly born, but find it burned down years ago. They then locate Father Spiletto, now disfigured and living in a monastery. Spiletto, barely able to speak, directs them to the ancient Etruscan cemetery where Damien's biological mother is buried. There, they discover a jackal's skeleton in the grave of Damien's mother, confirming his unholy birth. In the adjacent grave, they find the skeletal remains of Robert's actual son, his skull crushed.
Disturbed by their discoveries in Rome, Robert and Jennings realize their danger. They learn from Father Spiletto about the Daggers of Megiddo, seven ancient ceremonial daggers said to be the only weapons that can kill the Antichrist. Spiletto directs them to Bugenhagen, an archaeologist living in Israel, who has these daggers and knows the ritual to defeat the Beast. Robert, now convinced of Damien's evil, understands he must carry out this act to save humanity, despite the personal cost.
Robert and Jennings travel to Megiddo, Israel, and meet Bugenhagen in a remote cave. Bugenhagen confirms that Damien is the Antichrist and explains that the child has the mark of the Beast – the number 666 – on his scalp, hidden beneath his hair. He gives Robert the Daggers of Megiddo and instructs him that the ritual must be performed in a consecrated place, specifically an altar, and that a human hand must kill the Antichrist. As they leave the cave, a strong gust of wind causes a truck to lose its cargo, and a sheet of plate glass decapitates Jennings.
Back in London, Katherine, recovering from her fall but still disturbed, tries to escape the hospital. Mrs. Baylock, sensing Katherine's intention to reveal the truth about Damien, pushes her out of a high window, causing her death. The police rule it a suicide. Robert, devastated by Katherine's death and now without Jennings, commits to Bugenhagen's mission. He understands that the only way to stop the apocalypse is to kill Damien himself. He returns to the Thorn estate, retrieving the Daggers of Megiddo, preparing for the task.
Robert Thorn takes Damien to a nearby church, intending to perform the ritual as instructed by Bugenhagen. Mrs. Baylock, along with Damien's Rottweiler, tries to intervene, but Robert gets Damien onto the altar. As Robert raises a dagger to strike Damien, Damien’s guard dog attacks him. Police, alerted by neighbors who heard the commotion and saw Robert force Damien into the church, burst in. They see Robert with the dagger raised over the child. Misinterpreting the scene, the police shoot Robert Thorn dead. At Robert's funeral, Damien is seen holding the hand of the President of the United States, a chilling sign of his powerful future.

The Omen explores evil not as a human flaw, but as a supernatural, predestined force in Damien. The film questions whether evil can be recognized and stopped, even when it looks like an innocent child. Damien does not actively do evil acts; instead, evil flows through him, manipulating events and people around him, making him a passive yet terrifying force. This theme appears in Damien's unholy origin and the escalating, strange deaths that happen whenever he is threatened, showing an evil beyond human understanding.
“''When the Jews return to Zion and a comet rips the sky, and the Holy Roman Empire rises, then you and I must die. From the eternal sea he rises, creating armies on either shore, turning man against man, 'til mankind is no more.'”
Robert Thorn's initial deception—swapping his dead son for Damien—is driven by a desire to protect his wife from grief. This decision, born of love and desperation, leads directly to their ordeal. The theme explores how a well-intentioned lie can lead to catastrophic results. Katherine's loss of innocence is deep, as her maternal love turns to fear and then leads to her death. Robert's guilt is immense, as he realizes his initial choice brought evil into his family and the world, forcing him to face a moral dilemma.
“'He was born of a jackal! He's the son of the devil! He's the Antichrist!'”
The story emphasizes inescapable prophecy and destiny. Father Brennan and Bugenhagen's warnings, based on ancient texts, suggest that Damien's rise is preordained, making the characters' struggles seem pointless. Despite Robert's desperate attempts to intervene and change events by trying to kill Damien, the prophecy ultimately happens. This theme questions whether humanity has free will when faced with such powerful, supernatural forces, or if certain events, like the coming of the Antichrist, are simply inevitable, no matter what humans do.
“'He must be killed, Robert. Before he destroys us all.'”
The film suggests that institutions meant to protect are corrupt or ineffective. The church, through Father Spiletto, starts the deception. Later, the police, meant to uphold justice, mistakenly kill Robert Thorn, the only one trying to stop the evil. Even the highest office, the American presidency, is shown to be affected by Damien's influence in the chilling final scene. This theme implies that traditional safeguards against evil are either involved or powerless against the insidious nature of the Antichrist, showing a breakdown in societal and moral order.
“(Narrator, referring to Damien at the funeral) 'And he shall reign with them, for a thousand years.'”
The biblical 'mark of the Beast' identifying the Antichrist.
The number 666 serves as the definitive, undeniable proof of Damien's identity as the Antichrist. Bugenhagen reveals that the mark is hidden beneath Damien's hair on his scalp. This iconic biblical reference is a powerful symbol, instantly recognizable and evoking dread. Its literal manifestation on Damien's body transforms abstract prophecy into concrete, terrifying reality for Robert, forcing him to accept the supernatural truth and take drastic action. It's the ultimate 'smoking gun' in the narrative.
The only weapon capable of killing the Antichrist.
The Daggers of Megiddo are a crucial plot device, representing humanity's only hope against the Antichrist. These seven ancient, ceremonial daggers are steeped in religious lore and are presented as the sole means by which Damien can be killed. Their existence and the specific ritual required for their use (killing the Antichrist on consecrated ground) provide Robert Thorn with a tangible, albeit horrific, mission. They symbolize the desperate measures required to combat ultimate evil and act as the physical manifestation of the prophesied counter-force.
Bizarre and violent deaths that protect Damien and eliminate threats.
Throughout the story, characters who threaten or uncover Damien's true nature meet with bizarre, often gruesome 'accidents' that are clearly supernatural in origin. Examples include Holly the nanny's public suicide, Father Brennan being impaled by a lightning rod, and Keith Jennings being decapitated by a sheet of glass. These incidents serve to heighten the suspense and confirm Damien's malevolent power and the pervasive reach of the forces protecting him. They are a constant reminder that Damien is not just a troubled child, but a focal point for powerful, unseen evil.
Biblical prophecies and repeated warnings that guide the plot.
The narrative is heavily driven by prophecy, particularly from the Book of Revelation, which Father Brennan and Bugenhagen reference. These prophecies foreshadow Damien's identity and his eventual rise to power. The film also uses constant foreshadowing through the characters' unsettling dreams (Katherine's nightmares), the repeated warnings from the priests, and the photographic anomalies in Jennings' pictures. This device creates a sense of inevitable doom and slowly builds the terrifying truth for both the characters and the audience, making the plot feel predestined and inescapable.
