Humanity is going through difficult times - almost all the planets have fallen under the onslaught of invaders from nowhere, called the Masters. The cities are dilapidated, bloodthirsty zombies roam the streets - the fruits of experiments carried out on people, and clans of cyborgs who sold themselves to the Masters for new implantation technologies have divided zones of influence and keep the surviving people at bay. Nothing can shake the position of the all-powerful conquerors. But only until a Warrior appears on one of the captured planets. One single person seeking knowledge dangerous to aliens. And this warrior is a girl. Lima.
