Initial release: June 2, 2013, Through a series of oral interviews compiled by the narrator (an agent of the United Nations Postwar Commission), the story of the global war against zombies, "World War Z," is told. The story begins with the interview of a Chinese medical doctor who relates the story of a young infected boy who is the pandemic's "patient zero", although the origin of the zombie pandemic is unknown. It is implied that the boy was not the first victim chronologically, but his infection (as well as those he infected) is the first to be recorded, and marked the point the Chinese government attempts to contain the infection and concocts a crisis involving Taiwan to mask their activities. Regardless, the infection spreads to other countries by the black market organ trade and by refugees, with a larger outbreak in South Africa, bringing the plague to public attention.
As the infection spreads, Israel abandons the Palestinian territories and initiates a nationwide quarantine, closing its borders to everyone except uninfected Jews and Palestinians. It then puts down an ultra-Orthodox uprising, which is later referred to as a civil war. Pakistan and Iran destroy each other in a nuclear war after the Iranian government attempts to stem the flow of refugees fleeing through Pakistan into Iran. The United States of America does little to prepare because it is over-confident in its ability to suppress any threat. Although special forces teams contain initial outbreaks, a widespread effort never starts as the nation is deprived of political will by several "brushfire wars", and because a rabies vaccine, marketed as effective, creates a false sense of security. When the world recognizes the true extent of the problem, a period known as the "Great Panic" begins. Following the loss of New York City, the U.S. military sets up a high-profile defense at Yonkers, New York, but underestimate the enemy; their modern weapons and tactics prove ineffective against zombies, which "can't be shocked and awed" as they have no self-preservation instincts, and can only be stopped if shot through the head. The unprepared and demoralized soldiers are routed on live television, while other countries suffer similarly disastrous defeats, and human civilization teeters on the brink of destruction...WIKIPEDIA
