After ensuing in a lengthy chase with his new foe, Catwoman, Batman's utility belt gets swiped. Now, with his belt in the wrong hands, Batman must figure out how to find the cat burglar before she puts his belt to no good use.

Using his new ice powers, Mr. Freeze steals the most rarest and valuable diamonds all over Gotham. When him and Batman first cross paths, he tells the Bat he's the reason why he's a cryogenic monster. It's because of a much earlier chase between them, which led to a cryogenics lab. He will stop at nothing to make Gotham his own personal domain, unless the Batman can think of a way to stop this menace.
