Plot Since his last encounter against Batman, Victor Fries has made a home for himself in an Arctic cave with a newly adopted Inuit son, Koonak, and polar bear companions, Notchka and Shaka. His wife, Nora, remains in her cryogenic chamber while he seeks a cure for her illness. A research submarine surfaces through the frozen floor of the cave, shattering Nora's containment vessel, causing her to rapidly deteriorate. The submarine crew is then frozen by Fries. With no time to lose, Fries returns to Gotham City and enlists his old colleague, Dr. Gregory Belson, to help find a cure.

Barbara is taken to an abandoned oil platform, where Fries and Belson falsely tell her they need her for a blood transfusion to save Nora. Barbara reluctantly agrees to help. Back in Gotham, Bruce Wayne (Batman) and Dick investigate Barbara's kidnapping, which leads them on the trail of Belson, whose wrecked car Bruce had discovered earlier in a deep puddle on the night of his disappearance despite no rain.

They also deduce Fries's plan from a list of supplies used for an organ transplant that Belson left behind. As they head
