The blood sample has been fed into whatever instrument McCoy utilizes for this purpose. The Crewmember hands it back.

MCCOY

There’s poison here. It wasn’t present when we took this pup for specimen on Spahfohn. The radiation’s doing it.

CUT TO:

2 INT. ENTERPRISE BRIDGE—CAPT KIRK—(MEASURE)

CLOSE ON KIRK as CAMERA PULLS BACK to show us WHAT HE SEES in the view-screen. A strange silvery planet under a wan and dying red ember of a sun.

VOICE OF KIRK (OVER)

The magnetic radiation that has drawn us here to this desolate Rim of the Galaxy…the radiation that has somehow set our chronometers to running backward…is having a strange effect on all of us…

There is an O.S. BLEEP from an intercom.

3 INTERCUT—THE INTERCOM

as it flashes for Kirk’s attention.

4 KIRK—MED. CLOSE

as he flips the switch and the face of Spock appears on the intercom screen by his control chair.

KIRK

Yes, Mr. Spock?

SPOCK

Dr. McCoy has taken samples from each of the zoological specimens. They are growing younger.

KIRK

Conclusion?

SPOCK

So are we.

Kirk pauses a beat in perplexity. Troubled, deeply troubled. Strange things are happening.

KIRK

What is it that can reverse machinery and human beings?

SPOCK

Was that rhetorical, Captain?

KIRK

Unless you have some facts for an answer.

SPOCK

Do you believe in magic, Captain? Alchemy? The power of the supernatural?

KIRK

No.

SPOCK

Then I have no answer. There aren’t any in science, not for this. It’s the radiation, of course, but more than that—

5 FULL SHOT—THE BRIDGE—TILT/ANGLE

as a HIGH KEENING WHINE erupts in the chamber, the very air is suffused with a crimson glow, the banks of equipment begin running wild, fire breaks out in a shower of sparks on one panel, the ship rocks and bucks and SOUND PHASES UP AND DOWN the sonic scale.

SULU

(from controls)

Radiation intensity just jumped, Captain! Bang, we’ve got overload!

KIRK

(sharply)

Mr. Sulu, lay-in that parking orbit! Let’s not get any deeper into this radiation…

6 thru 9 SERIES OF SHOTS—HAND-HELD & TILT/ANGLE

MED. CLOSE on Kirk even as he delivers the preceding line. The ship rocks and bucks so violently, suddenly, that Kirk is thrown out of his control chair.

SMASH-CUT TO:

ANGLE ON BRIDGE as other crewmembers are tossed around like loose peas. The SCENE GOES RED again, eerily.

SMASH-CUT TO:

TILT/ANGLE IN CORRIDOR as the ship heaves and people are dumped, crashing into one another. Red haze.

SMASH-CUT TO:

INT. McCOY’S LAB as the shock wave hits and flasks shatter on the shelves, racks of equipment tumble and crash. McCoy and Spock are thrown against one another and both of them are thrown against the specimen table.

10 XTREME CLOSE SHOT—McCOY & BEAST
