INT-U.S.S. ENTERPRISE AUXILIARY CONTROL ROOM
[EPISODE NOTES: OPENING CREDITS FALL OVER OPENING SCENES]
[Carlson and another man are zipping the body of Monroe into a body bag.] 
DR. CARLSON: Alright, one, two, three.
[Carlson and two crewmen lift the body bag onto a gurney.] 
DR. CARLSON: Take the body to the ship's morgue.
MEDICAL OFFICER [nods]: Yes, Doctor.
[The medical officer takes the body.]
CAPT. BRANSON: Steven how did he die?
DR. CARLSON [sighs]: I'm not a hundred percent certain. But there are burn marks on his fingertips.
[Commander Williams walks over to the trio.]
LTCMDR. WILLIAMS: Obviously there was a short.
[Williams indicates the door control panel on the wall, which shows obvious signs of damage.] 
LTCMDR. CLARKSON: Is it possible that he could of opened the panel to work on it?
CAPT. BRANSON: According to his file he's a scientist not an engineer Steven find out how he died.
DR. CARLSON [nods]: Aye, sir.
[Doctor Carlson leaves the control room.]
[Captain Branson walks over to the console as Kyle starts examining the station.]
CAPT. BRANSON: Do you know what was he was working on?
LTCMDR. CLARKSON: Computer diagnostics, strictly routine. I've got security camera footage.
[Kyle activates the monitor in front of them and he, Branson, and Williams watch the footage. It shows Monroe working at the console until the picture is replaced with interference.] 
CAPT. BRANSON [confused]: What happened?
LTCMDR. CLARKSON: I don't know. It's a camera malfunction.
LTCMDR. WILLIAMS: Right before he was killed.
LTCMDR. CLARKSON: John, I recommend we drop out of warp, run a full diagnostic on the power distribution systems.
Captain Branson presses the com panel.
CAPT. BRANSON [to com]: Branson to Bridge drop us out of warp.
EXT-FEDERATION SPACE
Enterprise emerges from warp.
INT-U.S.S. ENTERPRISE MAIN ENGINEERING
[Clarkson, Williams and numerous personnel are working.]
LTCMDR. WILLIAMS: If I may be so bold, what exactly are we looking for?
LTCMDR. CLARKSON: Any indication that someone's been tampering with the ship's computers.
LTCMDR. WILLIAMS: I can assure you Commander that no one has been tampering with our computer systems.
[Kyle looks at her.]
LTCMDR. CLARKSON: Doctor Monroe died somehow and we have a duty to find out what happened.
LTCMDR. WILLIAMS: Could you be more specific?
LTCMDR. CLARKSON: Look, just check the major systems. Propulsion, navigation, life support. Look for anything out of the ordinary. Lindstrom and I will check power distribution, see if we can figure out what caused the power spike.
[They leave the engine room.]
CUT TO:
INT-U.S.S. ENTERPRISE POWER ROOM
[Clarkson and Lindstrom enter the room.] 
LTCMDR. CLARKSON: Okay, let's speed this up. You take the logs, and I am going to take a look at the… junction box.
[Clarkson opens the junction box and starts working in it. Lindstrom is at another console, punching keys.] 
LTCMDR. CLARKSON: I got nothing you?
ENS. LINDSTROM: Uh, give me a second… Wait a minute!
[Kyle looks over at him.]
LTCMDR. CLARKSON: What is it?
ENS. LINDSTROM: I think I got something here.
[Kyle walks over to him.]
LTCMDR. CLARKSON: What is it?
[Rapid beeping, lights flashing, Clarkson ducks out of the way of a coolant blast from the ceiling.] 
ENS. LINDSTROM: It's a coolant leak! Let's get the hell out of here!
[Clarkson gets to the door but Lindstrom is hit by the coolant blast. He screams and runs the other way, clutching his arm.] 
LTCMDR. CLARKSON [worried]: Lindstrom! Lindstrom!
[Both men leave the power room by opposite doors, Kyle into the corridor and Lindstrom into an airlock, closing the doors after themselves.] 
INT-U.S.S. ENTERPRISE AIRLOCK
[Lindstrom coughing.] 
INT-U.S.S. ENTERPRISE DECK TEN CORRIDOR
[Kyle coughing.] 
LTCMDR. CLARKSON [to com]: Clarkson to Lindstrom do you read me?
Video screen shows Lindstrom in the airlock, coughing up liquid.
INT-ENTERPRISE AIRLOCK
Lindstrom is coughing and takes a deep breath and activates his wrist com.
ENS. LINDSTROM [to com]: Yeah but my hand it hurts like hell what happened?
INT-U.S.S. ENTERPRISE DECK TEN CORRIDOR
LTCMDR. CLARKSON [to com]: I don't know. Just sit tight. We're going to need to shut down the leak and vent the room.
INT-U.S.S. ENTERPRISE AIRLOCK
[Lindstrom is inspecting his hand, which is covered in white residue. Static is heard over the communicator. Lindstrom attempts to re-establish the link.] 
ENS. LINDSTROM [to com]: Lindstrom to Clarkson do you read me?
INT-U.S.S. ENTERPRISE DECK TEN CORRIDOR
LTCMDR. CLARKSON [to com]: Lindstrom!
[The video screen shows Lindstrom shrugging. He is speaking but there is no sound.] 
INT-U.S.S. ENTERPRISE AIRLOCK
[A warning siren blares and lights on either side of the airlock door start flashing.] 
INT-U.S.S. ENTERPRISE DECK TEN CORRIDOR [RED ALERT]
LTCMDR. CLARKSON [to com]: Clarkson to transporter room lock onto Ensign Lindstrom and beam him out of the airlock!
CHIEF MACKENIZE [com voice]: I can't get a lock on him Commander something is blocking his signal!
INT-U.S.S. ENTERPRISE AIRLOCK
[The airlock begins to open.] 
INT—ENTERPRISE DECK TEN CORRIDOR 
[The video communicator screen shows the airlock open and Lindstrom get sucked out into space.] 
LTCMDR. CLARKSON [shocked]: Oh my God.

EXT-FEDERATION SPACE
Enterprise is at station keeping.
INT-U.S.S. ENTERPRISE DECK TEN CORRIDOR
Doctor Carlson scans Commander Clarkson.
CAPT. BRANSON: How is he?
DR. CARLSON [re: tricorder]: It appears he didn't inhale enough toxins to cause any permanent damage, although a few more seconds of exposure and it would have been quite a different story.
CMDR. IVANOVA: I assume this time we can definitely rule out random malfunctions.
LTCMDR. CLARKSON: Lindstrom found something. He was trying to tell me what it was when the leak happened.
CAPT. BRANSON: Who else knew what you were doing?
LTCMDR. CLARKSON: Alot of people knew we were running diagnostics, but no one knew we were in that particular room at that exact moment.
Captain Branson thinks.
CAPT. BRANSON: Have all non-essential personnel confined to quarters.
CMDR. IVANOVA [nods]: Aye, sir.
Commander Ivanova leaves deck ten.
EXT-FEDERATION SPACE
Enterprise is at station keeping.
INT-U.S.S. ENTERPRISE MAIN ENGINEERING [YELLOW ALERT]
[Commander Clarkson enters.]
LTCMDR. WILLIAMS: Commander you're just in time.
LTCMDR. CLARKSON: For what?
[Commander Williams shows him on the screen.]
LTCMDR. WILLIAMS: The sabotage we've been searching for.
[Commander Clarkson leans on the console.]
LTCMDR. CLARKSON: It's a virus?
LTCMDR. WILLIAMS: Yes it is.
LTCMDR. CLARKSON: Where did you find it?
LTCMDR. WILLIAMS: One of the navigational computers. There is evidence of it in communications and some of the propulsion systems as well.
LTCMDR. CLARKSON: It's spreading.
Commander Clarkson works at the console.
LTCMDR. WILLIAMS: Yes, and changing.
LTCMDR. CLARKSON: Changing?
LTCMDR. WILLIAMS: It appears to be re-writing itself as it grows. It is unlike any human engineered program I have ever encountered.
[The monitor shows binary code being translated into another script.] 
LTCMDR. CLARKSON: Oh crap.
LTCMDR. WILLIAMS: What is it?
LTCMDR. CLARKSON: I just ran it through a translation program. It's Klingon.
LTCMDR. WILLIAMS: Crap indeed.
CUT TO:
INT-U.S.S. ENTERPRISE CAPTAIN'S READY ROOM/SITUATION ROOM [YELLOW ALERT]
[Wall monitor shows the coding.]
CAPT. BRANSON: A Klingon virus?
LTCMDR. CLARKSON: It was probably downloaded during our last little encounter.
CMDR. IVANOVA: Well, if it's been there all this time, why are we just noticing it now?
LTCMDR. WILLIAMS: Well, in all likelihood, it was transmitted in a compressed format. It took a while to unfold, to spread to the point where it could adversely affect our systems. I think it probably happened during our return flight to Starbase 5. Since then, it's been dormant, waiting for some kind of a trigger.
CAPT. BRANSON: So, this virus killed both Ensign Lindstrom and Doctor Monroe?
LTCMDR. CLARKSON: Pretty much.
LT. MASON: But what would this virus help the Klingons to do what?
LTCMDR. CLARKSON: Possibly the fact that we're once again in proximity to Klingon territory. I think it was ultimately designed to take control of the navigational system. Fly the ship right to them.
CMDR. IVANOVA: If they get their hands on the Enterprise, they'll not only have access to Federation defenses but our fleet deployments.
BRIDGE OFFICER [com voice]: Captain Branson report to the bridge
CUT TO:
INT-U.S.S. ENTERPRISE MAIN BRIDGE [YELLOW ALERT]
They walk onto the bridge as Lieutenant Smith relieves the officer and reports.
LT. SMITH: We just began broadcasting a distress call.
CAPT. BRANSON: Shut it down.
Lieutenant Smith works at the console.
LT. SMITH: I can't I've been locked out of the communications system.
CMDR. IVANOVA: If the Klingons show up we're dead.
Captain Branson is worried.

[Lieutenant T'Lar is at her station keeping an eye on the long range scanners, as Captain Branson walks over to the engineering station.]
CAPT. BRANSON: Please tell me you guys have some good news?
LTCMDR. WILLIAMS: Theoretically, we should be able to cut power to the long-range transmitter.
LTCMDR. CLARKSON: It won't be able to send messages, but neither will the virus.
CAPT. BRANSON: Theoretically?
LTCMDR. CLARKSON: Well, it's pretty smart. So far, everything we've tried, it's been one step ahead of us.
[Kyle turns to Lieutenant Smith.]
LTCMDR. CLARKSON: Try it now.
[Lieutenant Smith works at her console.]
LT. SMITH: It's no good, Sir. We're still broadcasting.
CAPT. BRANSON: Where's the communications array?
LTCMDR. WILLIAMS: Deck 11 junction 23.
CAPT. BRANSON: Kyle, you're with me.
[Captain Branson and Commander Clarkson enters the lift.]
CUT TO:
INT-U.S.S. ENTERPRISE DECK 11 JUNCTION TWENTY-THREE [YELLOW ALERT]
[Captain Branson and Commander Clarkson enters the junction.]
LTCMDR. CLARKSON [re: tricorder]: Found it.
[Commander Clarkson opens the panel and he starts working on disabling the communications system, and power can be heard humming down.]
CMDR. IVANOVA [com voice]: Bridge to Branson we've stopped broadcasting a distress call
[Captain Branson presses the com panel.]
CAPT. BRANSON [to com]: Acknowledged Z.

[The engines fire up and the ship begins to move off.] 
INT-U.S.S. ENTERPRISE MAIN BRIDGE [YELLOW ALERT]
[A beeping sound can be heard.] 
CMDR. IVANOVA: What is it?
Lieutenants Mitchell and Carlson checks their station read outs.
LT. CARLSON: We're veering off course.
LT. MITCHELL: Navigational systems aren't responding!
LTCMDR. WILLIAMS: Damn it it's the virus it must of gotten into our engineering systems.
CMDR. IVANOVA: What's our course?
LT. MITCHELL: 2-3-2 mark 12.
LT. CARLSON: Commander, we've got another problem. It's our new heading. We're on a collision course with the nearest star.
[The view through the transparent viewer shows a distant star straight ahead as Commander Ivanova is shocked.]
INT-U.S.S. ENTERPRISE CAPTAIN'S READY ROOM/SITUATION ROOM
[The senior staff are around the table.]
CAPT. BRANSON: How do we fight this thing?
LTCMDR. WILLIAMS: We're still trying to figure it out.
CMDR. IVANOVA: And it's going to crash us into a sun?
LTCMDR. T'SHARA: Not exactly. A more precise calculation of our heading shows that we will not collide with the star, but rather make a close approach, near its coronasphere. The ship will survive, but the radiation will kill everyone on board.
[Kyle thinks.]
LTCMDR. CLARKSON: We could do a shut down and then a reboot.
CAPT. BRANSON: Do it.
[Both Commander Clarkson and Commander Williams leaves the ready room.]
INT-U.S.S. ENTERPRISE MAIN BRIDGE [YELLOW ALERT]
LTCMDR. WILLIAMS: We're ready.

CAPT. BRANSON [to com]: Good work can you give me warp?
LTCMDR. CLARKSON [com voice]: Yes we can
CAPT. BRANSON: Set course for Starbase Six warp factor seven.
Lieutenant Carlson works at the helm station.
LT. CARLSON: I'm sorry, sir. We had navigational controls for a second, but we just lost them again.
[The star comes back into view through the viewer, much closer than before.] 
CAPT. BRANSON [to com]: It didn't work we're still on course for the coronasphere.

CAPT. BRANSON: This thing is like a damn cockroach. You just can't kill it.
LTCMDR. CLARKSON: This should have worked.
CAPT. BRANSON: But what did we miss?
LTCMDR. CLARKSON: What if we didn't get every computer?
CAPT. BRANSON: What are you talking about?
LTCMDR. CLARKSON: What if there's a vessel out there that can transfer the virus from us to make us think that we destroyed it then re-upload it to our computer system?
[Captain Branson thinks.]
CAPT. BRANSON: You might be onto something.
[Captain Branson and Commander Clarkson leaves the ready room.]
CUT TO:
INT-U.S.S. ENTERPRISE MAIN BRIDGE [YELLOW ALERT]
[Captain Branson and Commander Clarkson enters as Captain Branson walks over to T'Shara.]
CAPT. BRANSON: T'Shara prepare a deflector beam we're going to see who is the puppet master.
[Commander T'Shara works at her console.]
LTCMDR. T'SHARA: Ready.
CAPT. BRANSON: Hit it.
She activates the pulse.

[Transparent viewer shows the D5-class cruiser.]
CMDR. IVANOVA: A Klingon vessel?
CAPT. BRANSON: Yeah I figured out that they were controlling the virus, Julia hail them.
LT. SMITH: No response sir.
LT. MASON: They're arming their forward torpedo launcher!
CAPT. BRANSON: Can we maneuver?
Lieutenant Carlson works at the helm.
LT. CARLSON: I'm sorry sir helm control is still off-line!
Captain Branson turns to Lieutenant Mason.
CAPT. BRANSON: Can you give me weapons?
Lieutenant Mason works at his console, gets nothing.
LT. MASON: I'm sorry sir.

The Enterprise continues on it's deadly course towards the sun.
CAPT. BRANSON [voice over]: Captain's log, supplemental, While on our way to Starbase Six for some well deserved R&R the Enterprise has become a victim of a Klingon computer virus that has taken over all ship functions and is hurling the ship towards a star, to make matters worse a Klingon battle cruiser has been revealed and has locked weapons onto us without our systems we can't defend ourselves
INT-U.S.S. ENTERPRISE MAIN BRIDGE [RED ALERT]
Transparent viewer shows the Klingon cruiser following the Enterprise.
CAPT. BRANSON: Have they fired?
LT. MASON: No, sir it seems that their torpedoes are just locked onto us but they've not fired.
LTCMDR. CLARKSON: Maybe they have orders to destroy us if the virus doesn't reach the sun to kill us all?
CMDR. IVANOVA: And we can't do another shut down with that vessel out there it'll just re upload the virus as many times as they want till we reach the sun.
Then Lieutenant Smith turns to report.
LT. SMITH: Captain we're being hailed.
CAPT. BRANSON: On screen.
Transparent viewer shows the bridge of the Klingon cruiser.
CAPT. BRANSON: I'm John Branson Captain of the Federation Starship U.S.S. Enterprise, why have you violated the Neutral Zone?
KLINGON COMMANDER [viewer]: We claim this system in the name of the Klingon Empire!
CAPT. BRANSON: This is the Neutral Zone you can't claim anything nor can you infect my ship with your virus release us!
KLINGON COMMANDER [viewer]: Surrender then Captain Branson and I'll consider it
Captain Branson stands at the helm and navigational stations, and just as he's about to surrender the transmission cuts out to seeing a couple of blue energy beams strike the neck of the D5-class vessel destroying the vessel.
CMDR. IVANOVA: Where the hell did those come from?
Commander T'Shara checks her scanner scope as it shows three Federation vessels U.S.S. Joshua Chamberlin NCC-2121, U.S.S. Hercules NCC-1657, and U.S.S. Athena NCC-1655.
LTCMDR. T'SHARA: Sensors have detected three Federation vessels approaching our position one of them is the U.S.S. Joshua Chamberlin Foley-Class.
Lieutenant Smith turns to report.
LT. SMITH: We're being hailed its Admiral Austin.
CAPT. BRANSON: On screen.
Transparent viewer shows the bridge of the Chamberlin and Admiral Joseph Austin.
ADM. AUSTIN [viewer]: Sorry we're late
CAPT. BRANSON: Better late then never sir how did you know?
ADM. AUSTIN [viewer]: Your wife Captain Smith came into the command center and told me that you're never late for your dates unless it's an extended deep space assignment or colony support
CAPT. BRANSON: Jessica is very smart.
ADM. AUSTIN [viewer]: Yes, she is you should be safe to do another shut down, we'll tow the Enterprise the rest of the way
CAPT. BRANSON [nods]: Thank you sir.
He nods and transmission ends.
CMDR. IVANOVA: That was close.
CAPT. BRANSON: You're telling me Z.
