Batman follows a strange trail of heists at various GothCorp offices, all by the same man: Mr. Freeze, a strange figure clad in a powerful suit and armed with a "freezing gun", a weapon that fires a beam capable of freezing anything into sheets of ice. Batman pieces together the stolen items and discovers that Freeze is building a massive ice cannon that is nearly complete, save for a single vital piece of equipment from GothCorp. Acting rapidly, he arrives at the GothCorp offices in time to engage Mr. Freeze, only to be partially frozen by him. As Freeze and his henchmen escape, he orders they leave behind one of their own, his legs accidentally frozen by Freeze's weapon. Batman chooses to help the man rather than chase Freeze.
