Clues to a crime spree lead Batman and Robin to an incarcerated Cluemaster—but things get twisted when the Dynamic Duo discover that thieves are forcing the villain's hand by holding his daughter captive.

Batman and Robin go to Blackgate to check out the Cluemaster (Arthur Brown) when they received clues to crimes that had already been committed. Robin learned he had been planning the crimes due to the thieves having his daughter, Stephanie, captive. Robin tailed the thieves and found their hideout (and Stephanie). Batman stopped the crime planned for that night.
