Detective Riley Parra grew up within the dangerous a part of city, the crime-ridden No Man's Land. Now, as a cop in a corrupt division, she strives to verify the tough streets she left behind aren't forgotten. One case leads her to the invention that No Man's Land is a battleground between angels and demons, a supernatural conflict that is been waged for hundreds of years. Thrown right into a world she by no means believed might exist and advised that she's the one probability of defeating evil.
