Brad Pitt, as the character Jerry Lane, has to save his wife Karen (played by Mireille Enos) and his two daughters from the zombie apocalypse when an outbreak of zombie infection spreads rapidly across the world. The big cities in the US are overrun by the zombie hoards. The family barely escapes New York, being rescued from the roof top just in the nick of time before the zombies could reach them. They are taken to navy ship that is offshore and a safe haven. The character Jerry Lane is a former United Nations worker who has special knowledge and skills that the government officials think will help them stop this zombie plague.
Jerry is very reluctant to go back to work for the government but it is the only way he can keep his family safe from harm on the navy ship. The first thing he does is take a scientist with him to discover the origin of the outbreak, which occurred in South Korea. The trail of clues leads him to Israel where the city of Jerusalem is protected from the zombies by a big wall. The zombies pile up, one on top of the other, and breach the wall. Jerry notices that although the zombies attack every healthy human they encounter, who when bitten then also turn into zombies, but the zombies pass by the sickly humans without harming them, which gives him a clue of how to stop the disease. Jerry's mission then becomes to reach the nearest laboratory of the World Health Organization which is the only place that might have a way that can stop the zombies so he can save the world an re-unite with his family.
Best part of story, including ending:
This movie expanded a zombie preparation sub-culture and made everyone think about what they would do if such a zombie attack occurred in real life.
Best scene in story:
The best scene is when thousands of zombies pile up on each other to climb over the wall in Jerusalem, because it is an awesome special effect.
Opinion about the main character:
The main character's courage is incredible. He is willing to risk his life to test himself as a human "guinea-pig" to see if the scientists have come up with a solution.
