This is it.
DOC ON TV: Never mind that now.
DOC: Why, that's me! Look at me!
- I'm an old man! - I'm Dr. Emmett Brown.
I'm in the Twin Pines Mall parking lot.
Thank God, I've still got my hair.
What's this thing I'm wearing?
This is a radiation suit.
Radiation suit?
Of course. 'Cause of all the fallout from the atomic wars.
This is truly amazing.
A portable television studio.
No wonder your president has to be an actor. He has to look good on TV.
MARTY: This is the part coming up.
This sucker's electrical but I need a nuclear reaction to generate the 1.21 gigawatts...
What did I just say?
... this sucker's electrical, but I need a nuclear reaction...
...to generate the 1.21 gigawatts of... - 1.21 gigawatts!
1.21 gigawatts.
DOC: Great Scott!
What the hell is a gigawatt?
How could I have been so careless?
1.21 gigawatts!
Tom, how am I going to generate that kind of power?
It can't be done, can it?
MARTY: Doc, look. All we need is a little plutonium.
DOC: I'm sure that in 1985 plutonium is available in every corner drugstore...
...but in 1955, it's a little hard to come by.
Marty, I'm sorry, but I'm afraid you're stuck here.
Doc, stuck here? I can't be stuck here.
I got a life in 1985.
- I got a girl. - Is she pretty?
Doc, she's beautiful.
She's crazy about me. Look at this.
Look what she wrote here.
That says it all.
Doc, you're my only hope.
Marty, I'm sorry, but the only power source capable of generating...
...1.21 gigawatts of electricity is a bolt of lightning.
MARTY: What did you say? DOC: A bolt of lightning.
Unfortunately, you never know when or where it's ever going to strike.
We do now.
This is it!
This is the answer.
It says here that a bolt of lightning...
...is going to strike the clock tower at 10:04 p.m. Next Saturday night!
If we could somehow harness this lightning...
...channel it into the flux capacitor...
... it just might work.
Next Saturday night we're sending you back to the future!
All right. Saturday's good.
