When Grace is sent to a juvenile facility awaiting trial for bogus charges, she has an idea that the Lord has sent her there for a reason. She and her five friends begin a trek through strange and frightening rooms, phases, dimensions, suddenly capable of strange powers, meeting other young people with powers of their own. She comes to the quick conclusion that God is ready to destroy the demon that oversees the place, and they are meant to be a huge part of that final battle. As she observes the suffering, her eyes fixed on God, she wonders what her part is going to be, will she be the Saving Grace for the lost children still trapped in the facility being tortured, persecuted, and murdered? Will her faith keep her safe? Or will she deny her Father and die with the rest of them?
