Damien the Antichrist, now thirteen years old, finally learns of his destiny under the guidance of an unholy disciple of Satan. Meanwhile dark forces begin to eliminate all those who suspect the child's true identity.

Damien Thorn: [to Mark] When you've met one platoon leader, you've met them all.
[mocking]
Damien Thorn: Attention! Eyes front! Chest out! Stomach in!
Master Sergeant Daniel Neff: What were you trying to do, Damien? What were you trying to do?
Damien Thorn: I was just answering questions Sergeant.
Master Sergeant Daniel Neff: You were showing off.
Damien Thorn: No. I just knew all the answers. Somehow I knew them all.
Master Sergeant Daniel Neff: You mustn't attract attention.
Damien Thorn: I wasn't trying to. I just felt...
Master Sergeant Daniel Neff: The day will come when everyone will know who you are but that day is not yet.
Damien Thorn: What you mean who I am?
[Damien has just seen the Mark of the Beast on his scalp, indicating he is the Antichrist. He runs out of the Academy building]
Damien Thorn: [shouting] Why? Why me?
Paul Buher: Do you know what exactly I do for Thorn Industries?
Damien Thorn: Not really, Sir.
Paul Buher: You should. You should know everything about the Thorn business. After all it will be yours one day.
Damien Thorn: And Mark's!
Paul Buher: And Mark's. Of course.
Damien Thorn: Why are you running away from me, Mark?
Mark Thorn: I know who you are.
Damien Thorn: You do?
Master Sergeant Daniel Neff: Mathematics good, Science very good, Military History fair, room for improvement.
Damien Thorn: Yes Sergeant.
Master Sergeant Daniel Neff: Physical Training is excellent. I hear you're quite a football player. Be proud of your accomplishments. Pride is alright when there's reason to be proud.
Damien Thorn: Yes Sergeant.
Master Sergeant Daniel Neff: I'm here to teach you but also I'm here to help you. Any problems you come to me. Don't be afraid, day or night, any advice. You understand?
Damien Thorn: Whatever you say Sergeant.
Master Sergeant Daniel Neff: We're gonna get to know each other. I see you're an orphan. Well, that's something we have in common.
Teddy: That's Damien's father in the back. My old man was on that team, too.
[pointing at picture]
Teddy: That's him. He was on the line. But Robert Thorn was quarterback. Even back then he was calling the plays for everybody.
Mark Thorn: [Coming in from Neff's office] You're next, Damien.
Damien Thorn: Teddy, don't ever talk about my father again. Do you understand?
Teddy: Can't you take a joke?
Damien Thorn: [Giving Teddy a long look] Yes.
[Turns to leave]
Mark Thorn: What was that all about?
Teddy: Your cousin really thinks he's somebody, doesn't he? My old man tells me the Thorns make their own hats because the stores don't sell them large enough for their big heads.
[laughter. Mark punches Teddy]
Damien Thorn: I love you, Mark. You're like my brother.
Mark Thorn: No! No!
Damien Thorn: You are my brother. And you mean more to me than...
Mark Thorn: No! The Beast has no brother! Don't call me your brother!
Mark Thorn: [Talking about Neff, that he might be the next platoon leader] That must be him.
Damien Thorn: He looks okay.
Mark Thorn: They're all the same.
Dr. Charles Warren: Richard, you know me to be a rational man, but what I'm about to tell you is not rational...

Title card: For such are false apostles. Deceitful workers whom lie and transform themselves to look like real apostles of Christ. II Corinthians, Chapter 11, Verse 13.
Murray: [the boys have been discussing Aunt Marion] Now, boys, just because Aunt Marion is getting on...
Mark Thorn: On our nerves!
Richard Thorn: Ann, give me the daggers!
Ann Thorn: [stabs him with the daggers] There are your daggers!
Richard Thorn: Ann?
Ann Thorn: I've always belonged to him!
[Richard falls dead as Ann lets out a primal scream]
Ann Thorn: Damien!
Dr. Kane: Hello, Ben? I need to see you urgently can I come down? No-no, there is something here that I just don't understand.
Dr. Kane: Mr. Thorn? They'll be alright. We've checked every boy for lung damage not a sign of it. Now they are gonna be nauseous for a little while but there is no permanent damage...
Richard Thorn: Doctor I don't care what it costs...
Dr. Kane: I assure you Mr. Thorn, they're all receiving the best care. Now there is one thing though, we made every possible test of blood damage, tissue damage and every boy was affected at some level though as I said not seriously. That is every boy except your nephew Damien.
Richard Thorn: Do you mean that...
Dr. Kane: No no no Mr. Thorn. He wasn't affected at all.
Ann Thorn: [after reading about Dr. Kane's death in the paper] Oh my god, it's horrible. We were just talking to him yesterday, when he wanted to do those tests on Damien.
Richard Thorn: Damien was not affected by the gas.
Ann Thorn: We can be thankful for that.
Richard Thorn: Why all the other boys and not Damien?
Ann Thorn: I don't understand. What did the doctor say?
Richard Thorn: The tissue tests he made indicate that Damien has a different cell structure.
Ann Thorn: Different?
Ann Thorn: What are you doing?
Richard Thorn: The daggers must be here somewhere.
Ann Thorn: What you want them for? No! No!
Richard Thorn: He's not human.
Ann Thorn: He's your brother's son, he's a boy you've loved for seven years.
Richard Thorn: The boy has got to die!
Dr. Charles Warren: Richard, I have to ask you something very personal.
Richard Thorn: We're friends.
Dr. Charles Warren: Can you tell what actually happened to your brother in London?
Richard Thorn: Why do you ask that?
Dr. Charles Warren: I've just opened a letter box that was sent from Israel. It belonged to Bugenhagen, they found it near his skeleton.
Richard Thorn: So?
Dr. Charles Warren: Did you know it was Bugenhagen who gave your brother the daggers to kill Damien?
Richard Thorn: What the hell are you talking about?
Ann Thorn: Charles, I heard about your reporter friend, what's her name?
Dr. Charles Warren: Joan Hart.
Ann Thorn: I'm so sorry.
Dr. Charles Warren: Yes, it's so strange. She got hit by a truck on a deserted highway.
Ann Thorn: I know.
Damien Thorn: Yes. Born in the image of the greatest power in the world! The Desolate One. Desolate because his greatness was taken from him and he was cast down. But he has risen, Mark, in me!
