During the ensuing fight, Mr. Freeze's assistant is killed, and his experimental transport vehicle, which contains his wife's cryogenically frozen body, is destroyed.

Back in Gotham City, Mr. Freeze resorts to kidnapping Barbara Gordon, the daughter of Police Commissioner Gordon, in order to use her as a donor for his wife.

In a climactic showdown, Mr. Freeze faces off against Batman and Robin, but ultimately decides to spare their lives and allow them to leave with the vital organ needed to save his wife.

Batman and Batgirl then transplant the organ into Mr. Freeze's wife, saving her life. Despite his initial gratitude, Mr. Freeze remains a wanted criminal and is taken back to Arkham Asylum. The film closes with Batman and Robin discussing the importance of fulfilling their duties as heroes, even in the face of adversity.
