By the end of the 21st century, the world had become a harsh place. After decades of natural and man-made catastrophes, nations fell, populations shifted, and seventy percent of the continents became uninhabitable without protective suits. Technological advancement strode forward faster than ever and it was the only thing that kept human society steady through it all. No one could have predicted the discovery of the Dream Walkers. They were people born with the ability to leave their bodies at will, unseen by the waking world. Having the potential to become ultimate spies meant the remaining government regimes wanted to study and control them. The North American government, under the leadership of General Rennet, demanded that all Dream Walkers join the military program. For any that refused to comply, they were hunted down and either brainwashed or killed.

The very first Dream Walker discovered was a five year old girl named Julia. And when the soldiers came for her at the age of twenty, she was already hidden away. A decade later found Julia living a new life under the government's radar. As a secure tech courier in the capital city of Chicago, she does her job and the rest of her time avoids other people as much as she is able. The moment she agrees to help another fugitive Walker is when everything changes. Now the government wants them both and they'll stop at nothing to get what they want.
