Synopsis:
One of Batman’s foes, Checkmate, learns that he received a lethal dose of radiation while hiding from the Caped Crusader. He sets up a plan to catch Batman in several traps and eventually expose him to deadly radiation as well. After Checkmate’s death, his henchmen lure Batman to the trap and believe the Dynamic Duo has entered the room of radiation, but they are outwitted. Batman escapes the trap and captures the gang.
