Synopsis:
Batman receives a tip to a crime being committed and arrives to capture Boss Baker. Another gang boss is present as well and escapes, but Batman learns they are both in pursuit of a treasure left by missing gang boss, Elliot Madden.

Batman follows the clues to the final location, but he himself is captured in a flying cage. Madden has planned the entire hunt as a means to capture the Caped Crusader. Batman however suspected that Madden was alive and also the tipster, so he substituted a robot for himself ahead of time. The real Batman tracks down the captured robot and arrests Madden.
