Okay, so I worked up an intro and included a breakdown of how things will develop in the five weeks of the onset. We know for a fact that the new series starts five weeks before the original series, and that it took five weeks for the world to crumble. We'll be following that same time line. What will be different for us is that we'll be set in New York instead of LA. 

FEAR. It took five weeks for the world we know to end. A pathogen highly contagious and all but undetectable enter earth’s atmosphere. It seeped into all of creation - invisible, odorless, and tasteless it tainted all. By the time patient zero felt the first sore throat millions of people were already infected.

Week One – Hospitals reached capacity. And the panic begun.
Week Two – Quarantine zones were established, resources were rationed, and transports come to a close.
Week Three – International trade discontinued. Oil wells dried up. And the stock market collapsed.
Week Four – Power failed, store shelves emptied, and the water tap ran dry. Hunger and despair set in.
Week Five – Chaos.

The walking dead gave way to the widespread outbreak of an unknown disease. Millions were infected within a single day after coming in contact with the contaminated. By Saturday, thousands of people had checked into hospitals across the nation, many of which were already past capacity and unable to assist any of their patients. They complained of intense pain, migraines and hallucinations and some began to exhibit mild bouts of violence. It wasn't until a patient killed a nurse and attempted to eat her flesh that people began to realize what they were dealing with.

What followed soon after was the swift collapse of our society. Within a few weeks, quarantined zones took over major cities and transportation to and from was shut down. Power went out, supply was lost, men and women who were sworn to protect were no where to be found. By week four, everyone had taken to looting and killing as they established the new rule of survival of the fittest. This was the onset of the walking dead.
