How well does Clark Kent know his own city? Are the threats targeting Metropolis new or something older and more dangerous than they seem? With mobsters being killed off and the Daily Planet staff hunting for answers, its up to Superman to discover what lurks in the underside of the city he thought he knew so well. Who is the Red Mist, and why has Superman never heard of someone so powerful and dangerous? And what is Lois Lane doing with Lex Luthor?
