Early in the movie "The Omen", just before the nanny jumped, she proclaimed “It’s all for you Damian”. In the background, a news photographer named Keith Jennings (David Warner) is present taking pictures.

Jennings will notice shadows in photographs of the nanny and of Father Brennan that presage their deaths. He shows Robert Thorn (Gregory Peck) the photos along with news clippings and biblical passages that suggest the coming of the Antichrist. He will then go with Robert to Rome to investigate Damien's birth. They learn that a fire destroyed the hospital, maternity records, and killed staff on duty. They find Father Spiletto in a monastery, severely burned, mute, blind in one eye and partly paralyzed. He directs them to the cemetery where Damien's biological mother is buried. Robert will realize that a jackal carcass is Damien's mother and a child's skeleton at the scene is his own son, murdered so Damien could take his place.

Robert calls his wife Kathy (Lee Remick) at the hospital to tell her she must leave London. Before she can do so, she is thrown to her death from a window. Robert and Keith meet Antichrist expert Carl Bugenhagen who says if Damien is the true Antichrist, he will bear a birthmark in the shape of three sixes. Carl gives Robert seven daggers with which to kill Damien on hallowed ground. Robert refuses to do so, but Keith remains convicted in their task. Afterwards, Keith is decapitated by a sheet of glass. Robert then reluctantly accepts his task.
