Based of "The Crazies"
Orem Valley is a small, quiet town in Utah, pretty much in the middle of nowhere. The population is a little under 300 and everyone knows everyone. It is in the middle of June and there's been a long drought since the beginning of May. The water supply has been getting low for the farms and the water supply has been infected with a virus, unknown to anyone in the town. Now, people of Orem Valley begin to act strange. They seem unresponsive to the rest of the world, and unable to control their actions.
The virus takes a little more than a day to settle into the body once it is processed. As you can guess, this virus is very easily and quickly spread because water is used out of the tap at least five times a day, whether it's for a shower, washing your face, or for a glass of water; no matter how, if it touches your lips, you can kiss your sanity goodbye. Once it is into the body, the person turns into an unresponsive, and savage human being. Though it could take up to two days to actually take full control, there are many signs to having the virus, like irritablility, and the pupils of the eye get smaller.
When you are taken over by the virus, you're brain goes into focus on only one thing, and that's killing anyone and anything in your path. Your looks become much more...sickly looking as in veins begin to show, sometimes skin changes color and even eyes turn colors. You become a savage beast and nothing can change it.
The military is also now getting into it, now that they have discovered this new undiscovered virus. They have begun a containment process, keeping anyone and everyone inside the town, infected or not. The military is sent for one reason only, and that is to kill anyone in the town that shows any signs of the virus, or even seems a possible threat others.
We are the few survivors of this horrible virus, and will have to group together to keep the 'Crazies' out and away from them, and to make it to the neighborring town, Price which is a bit larger, and hopefully uninfected. Everyone is an enemy, including the military, and nobody can be trusted, because the disease won't always settle in early.
