Plot
After a devastating war, there has been a realization that weapons are now too powerful and destructive. Thus ends the era of war fought in the "light" and begins the era of war fought within "darkness", a war fought with information and trickery, a war of spies. After the destruction of the spy team Inferno, their only surviving member, Klaus, sets off to create a team who specializes in "Impossible Missions". Impossible missions are missions that a spy team has already failed thus leading to higher security resulting in a chance of failure to be 90 percent.
The problem? The seven girls that Klaus has recruited are all washouts and bottom of the barrel for the spy schools they hailed from. Klaus only has a month to teach them everything he knows and in turn the girls will have to employ every possible trick to have a chance of surviving.
