to take the life of my son, John Conner.

Three times, we've been able to stop them.

It's only a matter of time before the machines figure out

they can just go back and kill one of us in infancy.

There's only one thing that can be done.

We have to terminate the creator of time travel.

(knocking)

Dr. Emmett Brown?

Yes?

(gun shot)

Huhhhhh!!!

Doc!!!

Come with me if you want to live.

You're telling me that not only do I invent time travel,

but in the future machines will use that technology to execute just one man?

Terminate.

Terminate just one man?!

That is what I'm telling you

Great scot!

Where is your hall pass? Get outta here you slacker!

(slicing) OHhhhh!!

This is heavy doc, if we're not careful, both of us are gonna be dead.

Marty, evil terminating robots or not, before we can accomplish anything

we've got to get your parents to that dance and we've gotta get you back to the future!

But how?!

Who are you?

Now listen to me very carefully.

He's got knives on his hands!

He's an absolute dream!

What are you looking at, butt-head?

(gunshot) UGHHH!!

You know I'm not the enemy...

If we stay the course, we are dead! We are all dead!!

I'm the only hope you have.

So why don't you make like a tree?

And get out of here!
