But when a modern-day military contractor called Archonite offered him an opportunity to serve his country and assist in a mission he was profiled as being perfect for, he couldn't say no. Only Donnie wasn't the one they really wanted subjected to this renewed Almighty project. And as he and Keith struggle to survive the shelter's manipulations and distortions, old grievances, jealousies and secrets threaten to destroy them both.
