Artric fear blankets Gotham City as a shimmering figure of destruction-the treacherous Mr. Freeze- unleashes a cold front of crime. Encased in a sub-zero cryosuit and allied with the sultry and deadly Poison Ivy-a botanical supermenace from the steamy jungles of South America-Mr. Freeze grips the city in a terrifying reign of villainy. But his iciest wrath is reserved for the only crime-fighting force with the ability to stop him-Gotham's guardians, Batman and Robin, who have a secret new partner of their own...Batgirl.
