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 bears 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 and causing her to rapidly deteriorate. Fries freezes the submarine crew and returns to
Gotham City, enlisting his old colleague Dr. Gregory Belson to help find a cure. Belson determines that Nora's only chance at survival is an organ transplant, but due to her rare blood type there are no suitable donors. Fries declares they will use a live donor, even if it means killing an innocent person, and bribes a reluctant Belson into compliance with a promise of gold that will end his current financial problems. After learning that
Barbara Gordon (
Batgirl) is a perfect match, Fries kidnaps her while she is on a date with
Dick Grayson (
Robin). 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. 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 investigate Belson's home and track Belson's broker, Dean Arbagast, who explains Belson's debts to them. In the process, Belson calls Arbagast from the oil platform, allowing them to learn where Fries has taken Belson and Barbara. They also deduce Fries's plan from a list of supplies used for an organ transplant that Belson left behind. As they head for the oil rig in the
Batwing, Barbara realizes Fries and Belson have been lying to her and escapes with the help of Koonak, who Fries had falsely promised that Barbara would not be harmed. Batman and Robin arrive and confront Fries and Belson, who accidentally starts a fire by shooting at the fuel tanks. Fries traps Batman and Robin and orders Belson to perform the operation despite the fire spreading rapidly across the rig, but Belson pushes Fries under some falling debris and attempts to escape, only to end up crushed and killed by the falling helipad while driving a speedboat. Batman and Robin escape and free Fries with Barbara's help and he in turn, despite his leg having been broken, helps them with saving Nora and Koonak, but while everyone else is put onto the Batwing, Batman is unable to save Fries, who plummets to his apparent death. Batman makes it back to the Batwing and they fly away just as the rig finally explodes. Fries, however, is revealed to have survived, and swims to safety with the bears. Sometime later, Fries has returned to the Arctic, and sees on a television in a research station that while the world believes him dead, Nora has been revived after an organ transplant funded by Wayne Enterprises, moving him to tears of joy as he walks away with his polar bears. ==Voice cast==
