As he and Steel join forces to remake Metropolis as a true City of Tomorrow, two of Superman�s classic villains take notice�and they have plans of their own. Plus, Kal-El reunites with the Dark Knight, Jimmy Olsen, and the Justice League to find out what he missed while he was away. And Jon Kent�s relief at his father being back is short-lived when he�s targeted by the mysterious Red Sin, who can do the unthinkable: injure both Jon and his father!
