Someone re-cap the TranZit story for me?

I've always loved the zombies story, it's so good. I kind of lost interest during Ascension when they decided if you wanted to experience the story you had to spend hours fiddling around with stuff to do some anti-climatic easter egg. Ever since, from Ascension to TranZit, I've been kind of lacking in my story knowledge. I know up to about TranZit, and I recently played Die Rise. The cutscene and stuff had really made me interested, and I want to try and catch up on the story.

So, could someone, in as much or as little detail as you are willing, explain the TranZit story to me?

Well, there is still a lot of things we do not know about. So we don't have everything. I don't even know what all we have.
