OK, so after the people that follow the religious nut throw the army guy out of the store, David decides that he wants to leave the store to save his son. The people that also want to leave are Amanda, Irene, Ollie, Dan, Bud, Myron, and Ambrose. They try to leave, but Mrs. Carmody and her religious freaks try to stop them. After they try to kill the group, Ollie, who has the gun, shoots Mrs. Carmody twice and kills her. They then leave. Bud, Ambrose, and Myron do no make it and are attacked by the monsters while heading toward the car. Irene, Amanda, Dan, David and his son head to Davids SUV. A giant monster kills Ollie in the process, leaving the gun on the hood of the car. David grabs the gun and the rest of the group get in the car and they drive away to safety. Now we only have David, Dan, Irene, Amanda and the son left. After they run out of gas, they agree that they do not want to die being killed by the monsters. There are only 4 bullets left. They agree that they must die, and David should be the one to pull the trigger. He shoots his son, Irene, Dan and Amanda and kills them. After crying and shouting in rage he steps out of the car where he sees a light coming toward him. It is the army, who have begun the process of destroying the monsters. The fog has lifted as well at the point the army comes in. As the army convoy drives by, David sees the woman from the beginning of the movie who left the store because she needed to get home to her two children. She did not die at all. We do not know what happened to the rest of the people in the store though. Pretty depressing ending, but a shocker and very different from traditional endings.
