If you read the book, don't expect much of the story to be the same in the movie. Actually, unless you count the zombies, it's more or less just the title. The book is much, much better than the movie! But then again, the book doesn't have air condition! ;)
The story is quickly told: Gerry lane is in Philadelphia with his family and witnesses a Zombie outbreak. He is a trained special force member and gets recruited by the US Navy to find the origin of the disease or better yet a cure. For his service his family can stay on a ship, far away from dangerous, coterminous zombies. Then he travels a lot and behaves rather stupid:
- He doesn't tell anyone what he found out about zombies
- he makes really strange assumptions that by chance turn out to be true (for example when he sees the people avoided by zombies and "just knows" they are sick)
- He obviously is rather reactive and pain resistant, but still one should rest a bit more after serious injuries
For everyone who made it through the scientist's rant: The movie ands well and Brad Pitt survives. But still, a nice zombie move with certain flaws!
