Year: 2012
Day: December 19th

After a meteor has crashed in to earth, the world has broke into chaos. People are going crazy. It is believed thataliens are attacking the human race. The whole world broke into fear.
After months of suffering, small groups of survivors will come together discover how to stop the world from ending and save the human race for eternity...or thats what they think.
Weeks later...they realize they're dealing one of the most powerful creatures in the whole universe. They realize this war will go down in history as the war that ends all wars. Only one side will win the war to "End All Wars."

Thats what i have so far...
Also, the title is "48 Hours...which means they have 48 hours to save the world.
