They were in a small town and they were trying to get to the gasoline. They had bordered themselves up in a house owned by this young guy and his wife. The one (business looking) guy wanted everyone to go downstairs and board themselves up, but this other guy disagreed because he said they would get stuck. So the guy went downstairs and locked the door. He was down there with his wife and sick daughter. The folks upstairs were using pieces of wood to nail against the windows and doors, but they needed to go into the basement to get more wood, but the guy downstairs with his family did not want to open the door....fast forward...fast forward... the young wife insisted that she could drive the truck so they could get gasoline....fast forward...the husband and the guy got on the back of the truck....this is where I had to go in another room to comb my hair for work...lol...came back in and the guy had fallen off the back of the truck.
There was another woman in the movie who was holding a shot gun and said the zombie people (me paraphrasing...lol..) were moving so slow that the people in the house could run right past time.
This might help... The guy (he was black) that insisted they stay upstairs and board up the windows and doors was the same creepy guy that played the coroner in Final Destination that and shoved the corpse in the furnace. I think he played a creepy guy in the movie "I Still know what you Did last summer" can't remember.
Now if you can guess the movie from my description, I'm absolutely going to crown you KING of the Movie World...

I might have seen the trailer for the Devil, the name sounds familiar, but I've only seen it once.
