Set beneath the real-world military base at Pine Gap. The story follows a small team of elite soldiers who are sent into the bowels of the complex to rescue a top scientist from an experiment that has apparently gone awry. In the bowels of the base they encounter the mysterious survivor Eve. It quickly becomes clear that the facility is a testing ground for something far more sinister. The team must now, with Eve in tow, fight their way through escaped inmates and fight off the devastating psychic attacks rooted in their own darkest, primordial fears.
