Ira Quimby, who once used a special rock to gain super-intelligence, has found that he now can gain more intelligence due to exposure to sun-light alone. Using his sun enhanced mind, Quimby creates an invisibility device to break out of prison.
Sure enough, once out of jail, Quimby reorganizes his I.Q. Gang and uses his intelligence to create special devices to aid him in fantastic robberies. This gains the attention of Hawkman and Hawkgirl, and the two try to take down their old foe. However, I.Q. is ready for them and has created a remote control flying net which he tries to use to dash the two heroes against the side of a cliff face. However, they manage to break free and track I.Q. back to his hide-out.

In spite of the fact that Quimby has setup various illusion devices (one which renders them invisible, and another which makes everyone's limbs look like they're spread out all over the room), Hawkman and Hawkgirl defeat I.Q. and his gang when they smash the devices creating the illusions.

After turning I.Q. back over to the authorities, they confiscate his high-tech weapons and store them on their Thanagarian ship to insure they don't fall into the wrong hands
