In Roman-ruled Britain, a young Roman soldier endeavors to honor his father's memory by finding his lost legion's golden emblem.

Marcus Aquila: [about Esca] He's not a slave. And he knows more about honor and freedom than you ever will.
Guern: My shame would not allow me to tell you this before... but I watched your father die. Whatever anyone tells you, he was *not* a coward. He stood his ground to the very end. I saw it. The last Roman to hold the eagle was your father. The order, sir.
Marcus Aquila: You've honored my father's memory enough. You don't have to do this.
Guern: No. When I ran from your father... I ran from myself. Give the order, sir.
Marcus Aquila: Prepare to defend the eagle!
Marcus Aquila: [from trailer] Who has the eagle?
Guern: [pointing to Esca] He knows. He's one of them.
[preparing to lead a sortie from the fort]
Marcus Aquila: [whispering] Mithras, lord of light, father of our fathers, let me not bring misfortune to my legion. Mithras, lord of light, father of our fathers, accept whatever sacrifice that I may not bring misfortune to my legion.
Marcus Aquila: [shouts] On my command, we form testudo! Ready... open the gates!
Esca: I hate everything you stand for, everything you are, but you saved me, and for that I must serve you.
Esca: How can a piece of metal mean so much to you?
Marcus Aquila: The eagle is not a piece of metal. The eagle is Rome.
[from trailer]
Esca: [coldly] You're my slave. Do as I did for you, and you'll survive.
Aquila: No Roman can survive north of the wall alone. You can't.
Marcus Aquila: Then I'll take Esca. I can use his knowledge. He speaks the language.
Aquila: Esca?
Marcus Aquila: Why not?
Aquila: 'Cause he's a Briton. He may not be from the north of the wall, but he's a Briton, and he will slit your throat the minute you're alone.
[first lines]
Marcus Aquila: Marcus Flavius Aquila, Fourth Cohort of Gaul, Second Legion, come to relieve the command.
Lutorius: Lutorius Drusillus Salinator, acting senior officer.
Marcus Aquila: Where's the garrison commander?
Lutorius: He left this morning, sir. Couldn't wait to get away.
[Marcus regains consciousness after his surgery]
Marcus Aquila: Did I shame myself?
[Esca shakes his head]
Marcus Aquila: Thank you.
Marcus Aquila: [to Esca] You're free, my friend.
[last lines]
Esca: So what now?
Marcus Aquila: You decide.
Marcus Aquila: Who has the eagle?
Guern: They say the Seal People have it.
Marcus Aquila: How do I find them?
Guern: [pointing to Esca] He knows. He's Brigantes.
Marcus Aquila: [praying] Mithras, lord of light, please help me, father of our fathers. Help me lead my men well. Do not let me dishonor my legion. Please help me regain my family's honor.
Roman Soldier: Where's our newly-minted commander?
Lutorius: Probably unpacking his rule book.
[after being told he has been discharged from the army, Marcus asks to be left alone. Walking away from the room, Stephanos hears a scream of pain, and turns back in alarm]
Aquila: Stephanos, leave him. There's no medicine for that.
