Picking up from recent issues of BATMAN, the origin of Clayface is revealed—and a new mystery is introduced!
James Gordon arrives on the scene of a jewelry store robbery in progress, and after trading himself for the security guard hostage inside, guns down the robbers in cool blood. Then when Batman shows up, it is revealed that James Gordon is really Clayface.
Clayface escapes when Batman hesitates when Clayface changes into Natalya. This fact doesn't sit well with Batman who goes back to the Batcave to try to figure out where Clayface is keeping Gordon.
Meanwhile, Gordon breaks free of his bonds and creates a make-shift Bat-signal, which alerts Batman to his location. Batman rescues Gordon but not before Clayface escapes again this time with a baby buggy full of valuables.
