Summary: The virus breaks out in Las Vegas and the team are forced to believe in what is being said in the news. It's not long before Grissom starts his own experiment to see if he can cure the virus once and for all but not before all hell breaks loose.

Disclaimer: I don't own CSI or the 28 days later series, I never will and it makes me sad to keep saying it D:

"GRISSOM!" Catherine's shout were audible from a mile away and he heard her even before he had exited his SUV. He got out and headed straight for here, no doubt she'd already heard what had happened at the scene.

"I guess you've heard?"

"Yeah David came in, scared to death saying that the dead body attacked him." Confusion spread across her face as she realised what was said. 'No matter how much I keep saying that, it still doesn't seem to make sense.' Catherine shook off her thoughts and continued to wait for Grissom's reply.

"That's exactly what happened except Jim shot the guy twice in the head afterwards. I know what your thinking and I'm going to say this to you and I don't want anyone else knowing until I'm sure. Got it?" He didn't wait for her replied instead he began to walk towards the lab and continued. "I think that virus has somehow made contact into America and we're the first to get hit. I want this kept down low but everyone must carry their gun. Emphasis on the must."

"What's that going to solve? This needs to be broadcasted so they can contain it before the virus gets out of hand."

"I realise that but from now on this is the primary case. Nothing else is as important. I'm going to run tests and try and solve this myself. I'll need the full co-operation of the DNA lab so I want Greg as well as day shift and swing shift's DNA techs. Nothing get's out. If cases come in I want you to make sure you find out the MO that way we can decide whether it's another victim of the rage virus then we'll need the body guarded by dozens of officers if it turns then it has to be killed. We'll need one to test on. Simple."

"Isn't that a bit drastic, I mean if you keep using the cops to guard suspected carriers then the P.D department will get suspicious and the whole thing will get out. Testing on a human is going to be hard to get away with as well. Look I'll try my hardest to help you but I can't guarantee anything."

"Fair enough. While this is going on I want you to keep a close eye in Lindsey, we don't know who or where the current carrier is and it's soon to break out. Keep her here if you can."

"Okay. Doc also said he wants to see you ASAP. Probably to share some light on the deceased David brought in."

"Right I'll fill you in later." Grissom headed straight for the morgue knowing that this is going to be the most difficult case he's ever worked on. 'How am I going to go around this?'

"What have you got for Al?" He paced into the room whilst putting on his lab coat, latex gloves and wearing a face mask.

"I know something weird happened out there but it doesn't mean it's going to happen here. I haven't started the Y incision yet but I wanted your opinion on what this could be."

"It's extra precautions, if this is what I think it is then I don't want you opening him up. His COD is the least of our problems. Keep away from any blood that he has left."

"It's that virus thing isn't it?"

"That's what I'm thinking. Keep it to yourself all I want here is a sample of his blood."

"Well that's the easiest autopsy I've performed! I've already got a sample there waiting for you. Keep me posted please Gil."

"Thanks, I will do."

Grissom took the sealed beaker up to the lab where he could analyse it under a microscope. That's the only thing he can do to find out exactly what they were dealing with without putting the city or country in danger. He also needed to research this virus more. 'From now on, all my time goes into this.'

He printed a few pages from different sites off the internet so he could compare the details to his sample. He placed a drop of the blood onto a glass slide and placed another on top. The blood spread at reaction to the pressure he gave it and slid the glass under the microscope. Gil knelt over and looked at the sample. The blood cells present were taken over by some sort of artificial membrane which caused a violent reaction, each cell seemed to bounce around in it's boundaries.'This is it.'

"Grissom? Usually I run the samples what are you doing?" Greg's presence caused Grissom to turn around in shock. It soon passed and he knew he had to get Greg's opinion on the blood.

"Come here and tell me what you think of this."

"Sure." He bent over and looked into the microscope and his brows furrowed at the picture in front of him. "What is this?"

"It's blood Greg."

"Well yeah but I've never seen it react like that before. Did you add some sort of chemical to it?"

"No it's how I found it. That virus outbreak in Britain, I think this is it and it's going to spread here. I need your help to figure out a cure."

"Um…Okay but this seems a little supernatural for you, I thought you didn't believe what was being said on TV?"

"I didn't until I saw it for myself. I'm going to get all our CSI's on this, we need to find a cure before this becomes another outbreak."

He exited the lab and went into his office where his migraine gripped a tight hold onto his head again. It was throbbing around his temples and if he didn't take his prescription now then it will eventually take over his whole head. He'd only ever let it do that twice in his whole life time and it was the worst pain he'd ever felt. Reaching for the bottom draw of his desk he pulled out the little container that held only a few pills left. Grissom took them dry, not bothering to find some water and sat at his desk and continued a search on the virus. He needed to learn everything he could.

"Hey, Griss? What's going on? We've just had a call for 5 dead bodies and that they all have a large flesh wound to the neck, almost looks like a bite. Have we got a gang of wannabe vampires on loose?" Sara seemed like the millionth person to interrupt his thoughts.

"No it's a lot more serious than that."

"Like what?" She asked.

"We've got an outbreak of the 'rage' virus."

"You are kidding me?" Her eyes widened at his response, hoping he was playing another one of his retarded jokes.

"I'm afraid not. This is going to get bigger if we can't contain it. Don't send any of our CSI's out there it's not safe."

"Nick and Warrick have already gone to a couple of the scenes, apparently you said Nick can have the first crime that comes in."

"Ring them we need to get them back here, warn Jim as well. I need to check in with Greg." Grissom practically ran past Sara and out the DNA lab.

'This has to be a mix up' Sara wandered out of his office attempting to ring her friends before something happened to them.
