Strange happenings in Garfield City, NY: a banker hands out money and insults; a respected scientist laughs and dances; nearby, dogs howl; a scientist, Cranlowe, has invented a weapon to stop war; other cases of insanity occur; a well-organized gang kidnaps and murders, trying to get Cranlowe’s super-weapon.
The gang seemingly kills the Justice, Inc. team; Benson, Mac, Josh, and Smitty use the opportunity to go undercover.
Under terrible threats, Cranlowe won't reveal the weapon's formula.
The mind control device, an invention abandoned by Cranlowe, uses high-frequency vibrations unique to each individual.
Benson's mind is apparently controlled; later, he fights a mind-controlled Smitty, who has easily overcome Josh, Mac and Nellie.
