A team of special forces soldiers approach the designer of a high-tech military compound to investigate the disappearance of another team guarding the facility. The compound, known as a Temple, is an artificial intelligence powered facility designed for interrogating high level prisoners. Upon entering the Temple, the soldiers quickly find the earlier team horrifically slaughtered but no evidence as to who is responsible. Almost immediately, the crew begins to experience strange and horrific supernatural phenomena as they attempt to uncover who killed the previous team. Soon enough, they find a lone survivor, a dangerous terrorist who may hold the key to who killed the soldiers. But they find that there is more to learn and a dark secret that they share may hold the key to their survival.
