Synopsis:
Batman and Robin face a criminal, "Gadgets" Blore, using a new weapon that gives the Dynamic Duo opposite charges. Whenever they come near one another an explosion occurs, the first of which destroys the weapon, but leaves them in the altered state.

Batman builds a Robin robot that the Boy Wonder can control by remote. It is damaged in the next encounter with "Gadgets" which reveals to the crook that it is not the real Robin.

When "Gadgets" strikes again, one of his gang captures the controls from Robin and uses the robot against Batman. The crooks take the robot back to their hide-out, but it is really the true Robin. The accident which damaged the robot initially removed the charge from Robin, restoring him to normal. Batman arrives and together with Robin, defeats the gang. Eventually Batman's charge wears off as well.
