All I have for you is a word. 
Tenet. 
It'll open the right doors...
and some of the wrong ones, too. 
Use it carefully. 
To do what I do...
I need some idea of the threat we face. 
As I understand it...
we're trying to prevent World War III. 
I'm not seeing Armageddon here. 
No. 
Something worse. 
I gather you have an interest...
in a certain Russian national. 
Why did you bring me in? 
Do you really want to know? 
He can communicate with the future. 
Time travel? 
No. 
Inversion. 
Aim it and pull the trigger. 
You're not shooting the bullet. 
You're catching it. 
Whoa. 
Well, I've seen too much. 
Well, we'll try and keep up. 
Your duty transcends national interests. 
This is about survival. 
Seems bold. 
"Bold" I'm fine with. 
I thought you were gonna say "nuts." 
This is where our worlds collide. 
How would you like to die? 
Old. 
You chose the wrong profession. 
The hell happened here? 
Hasn't happened yet. 
There are people in the future who need us. 
Hurry up! 
Who need Tenet. 
We need to save them, here and now. 
This reversing the flow of time...
Doesn't us being here now...
mean it never happened? 
You want to crash a plane? 
Well, not from the air. 
Don't be so dramatic. 
Well, how big a plane? 
That part is a little dramatic.
