A team of trained operatives are sent to a prison facility to investigate the disappearance of another covert operational unit. Soon after arriving they discover the bodies of their men and then find themselves trapped inside after a full lock-down. They watch the surveillance footage of the soldiers being killed by unseen assailants, and soon after they begin to experience strange and horrific phenomena as they attempt to uncover what is killing them!
The building is a highly evolved AI named Temple which is in effect a huge lie detector. The team who have been killed and the team sent to rescue them had previously been on a tour of duty in Afghanistan. Whilst in Afghanistan they were questioning a village elder and things got out of hand and they massacred the village; they have been covering this up and this is what Temple wants to expose and why they are being punished.
