Under the Dome2013

Julia Shumway:
What is that noise?

Phil Bushey:
I don't know, but it's jamming our broadcast. Kind of sounds like the alien from Aliens.

Julia Shumway:
Well, all the police walkies are making the same sound. Is Dodee picking up any military chatter from outside the dome?

Phil Bushey:
Oh, screech is jamming that, too. And if it's this loud, then the source is probably close.

Julia Shumway:
How close?

Phil Bushey:
Best guess? Mile or two.

Julia Shumway:
So it's inside Chester's Mill? [Phil sighs] Listen, if it's that close, maybe we can find it.

Dodee Weaver:
[Enters carrying some sort of device] One step ahead of you, Julia.

Julia Shumway:
Do I even want to know what that is?

Dodee Weaver:
Us radio heads call it a "yagi". I rigged it to locate the source of the screech using frequency triangulation. Look, whatever this screech is, it can't be a coincidence that it started just as the missile was about to hit the dome.

Julia Shumway:
You think the dome was trying to scream?

Phil Bushey:
Or protect itself.

Dodee Weaver:
Who knows? But if it was, it might be what's generating the dome itself. We just have to follow the signal to the power source.

Julia Shumway:
Well, if that's true, then if we can track it down...

Dodee Weaver:
Maybe we can turn it off.
