@starkatt Four teenagers at cure-camp, waiting to see which one is the actual devil, but it's really their camp counselor, and they're saved by one of the other counselors who is also a demon, but a different kind that's been sent undercover to document the corruption. They help the kids get out by teaching them to invoke their own inner spiritual powers, made stronger by the power of shared empathy and respect for each other's identities, and escape what turns into a hellmouth behind them.
@literorrery @mawr I really do recommend playing We Know the Devil (and getting all four endings) if you haven't.
@starkatt @literorrery the original post was the actual plot of a game. :3
