This feature-length spin-off of Batman: The Animated Series follows the dynamic duo as they battle their ice cold, age old enemy, Mr. Freeze. In his latest nefarious plot, Mr. Freeze has abducted Batgirl as the organ donor needed for a deadly experiment meant to reanimate his old wife, who, until her cryogenic chamber was shattered, had been frozen until a cure was found for her otherwise terminal heart disease. Unless Batman and Robin can rescue her on time, Batgirl will lose her life in a highly illegal heart transplant operation. Featured voices include Kevin Conroy as Batman and Michael Ansara as the infamously monotone Mr. Freeze.
