Synopsis:
Batman and Robin thwart a series of robberies in which the victims help the robbers. Batman begins to suspect that the men have been hypnotized when he receives a mysterious phone call as Bruce Wayne. Bruce then helps crooks with another robbery. Robin stops the crime, and Bruce can't explain his actions.

Batman deduces that all of the victims including him are part of a civic counsel. He monitors each member the following evening. When the mystery caller targets Myron Mycroft, Batman hopes to stop the crime. Instead, he is nearly killed in an ambush. He does save Mycroft, who learns that Batman is following orders.

Mycroft is actually the master behind the crimes. Seeking to prove Batman is under his control he orders Batman to blow up Wayne Manor with explosives. The Caped Crusader complies with the order, but Robin and Alfred have replaced the explosives with smoke bombs. Batman finally realizes that a watch given to him by Mycroft at the counsel meeting contains a device which makes him follow orders. He removes the watch, then apprehends Mycroft.
