TURING & ALEXANDER (quietly): 

"Heil Hitler."

Turns out that's the only German 

you need to know to, uh 

-- Break Enigma.

Alan Turing :

What... What if... 

What if Christopher doesn't have to search 

through ALL of the settings?

 

What if he only has to search through ones 

that produce words we already KNOW 

will be in The Message? 

JOAN: 

Repeated Words; 

PREDICTABLE Words. 

Alan Turing :

Exactly. 

JOAN: 

Look, look, like this one :

"0600 hours. 

Weather Today is clear. 

Rain in The Evening. 

Heil Hitler." 

Well, that's it. 

Exactly. 

They send a weather report every day at 6:00 a.m. 

So that's - 

That's Three Words we KNOW 

will be in EVERY 6:00 a.m. message -- 

"Weather," obviously, a-and... 

"Heil" bloody "Hitler". 

Heil bloody Hitler. (laughs) 

(pants) 

Here's the 6:00 message from this morning. 

TURING: 

Hugh, the, uh, the right-hand letter wheel, set them to... 

I know, I know. "Weather" and "Hitler." 

Peter, John, run voltages through those letters, 

through the back scramblers.

PETER: 

So we'll use the loops? 

TURING: 

Yes. Joan, what was the last 6:00 a.m. message?

Oh, my God. 

Wh-What happened? 

-Did it work? -Alan? 

ALEXANDER: Alan! Alan! 

I need a new message.

and auf punkt one... degree west."
