Synopsis:
While Batman is away on a secret mission, Robin breaks up a robbery by the Brady Brothers. He is assisted by a tiny costumed man called Ant-Man. Robin suspects Ant-Man is really Batman exposed to chemicals at the lab of Professor Hanson, but when Ant-Man turns on Robin and steals some jewels, Robin realizes his mistake. He plans and executes a trap to ensnare the miniature mobster, who is revealed as rival gangster Jumbo Carson.
