Synopsis:
Batman and Robin use their crime files to determine the men behind several robberies. When one of them has an alibi, Batman realizes that someone is using their trademark criminal methods. He suspects the cleaning woman responsible for the police records room and questions her. The woman denies the charges, but evidence at her home convinces Batman that she is guilty.

Batman returns and is captured by the cleaning woman and her men. He escapes and tracks down the woman's mob on their next robbery. He then arrests the cleaning woman, having gained evidence against her and the men who were framed.
