Epidemic

In the year 3000 the world has gone into a frenzy. The government fell and wars broke out. Pinning brothers against brothers. A new Government rose from the old and built a wall that city off from where the rebels are located. It was a perfect Utopia, called 'Florence'. They found cures for illnesses and other amazing discoveries. Until a plague broke out. The deadliest plague that has no cure.
Stephanie Russo, 23 year old, the most wanted criminal in 'Florence' found herself delivering two teenage siblings, Marie and Christopher, to the rebels outside the walls of Florence. She knows the danger of delivering them but the pay is wonderful so she's willing to do it for the money. With World War VIII between the government and the rebels the police aren't too worried about her, but there are other people she needs to be worried about.

Will she deliver the kids safely with no problems? Or will she get caught? Or worse killed?

She doesn't only have to worry about catching the plague. She has to worry about surviving.
