Batman and Commissioner Gordon are forced into a tight corner as Clayface embarks on a murder spree throughout Gotham City. But hope surfaces when the Mad Hatter emerges as an unlikely ally.
Clayface breaks into the Gotham City Stock Exchange, and after killing his own crew Batman shows up. Clayface is able to escape because Batman's ne containment device can't trap the shape changer.
Later, Batman visits Arkham Asylum where he learns that Clayface found out about Natalya connection to Batman via the Penguin who heard it from the Mad Hatter. So after visiting the Penguin, and threatening him, Batman pays a visit to Commissioner Gordon. Batman then tells Gordon his plan to catch Clayface.
Later that night, Clayface breaks into warehouse to steal the Cat's Eye Diamond, but he is conered by Batmen, and more Batmen. Clayface tries to make break for his but is too rattled by the Batmen, and can't change shape fast enough. This gives the real Batman time to use the Batplane to capture Clayface and reveal the Batmen are Gordon and his officers.
Back a Arkham, Clayface is locked in a new cell that should keep him prisoner for a long time, but even Gordon know all Clayface needs is a tiny crack to escape once again.
