Batman and Robin track down Mr. Freeze. During the fight they take possession of the cold gun. Robin then takes the gun back to the hospital while Batman continues the fight. Mr. Freeze nearly kills Batman by freezing him, but the Caped Crusader uses a thermal unit to thaw out quickly. Before returning to the hospital to see that Harriet's surgury was a successs, Batman apprehends Mr. Freeze and his gang.
