Based on the animated direct-to-video movie Batman & Mr. Freeze: Sub-Zero! Mr. Freeze's beloved wife, Nora, desperately needs an organ donor, and there's only one candidate at hand--Barbara Gordon. And if Mr. Freeze has his way, she doesn't get any say in the matter. Can Batman and Robin rescue her in time? And if they do, does an innocent woman pay the ultimate price in the process?
