Failing to destroy Batman and Robin, the Minstrel enacts "Plan High C." He shakes the building of the Gotham City Exchange, and promises to send it crumbling down if his demands are not met in one hour. Batman assumes cutting off the building's power will thwart the villain, but when that plan fails, it's up to the Dynamic Duo to track down the Minstrel before it's too late.

Using resurrected scarab beetles, King Tut concocts an ancient mind control potion, abu raubu simbu tu. Chief O'Hara is the first under his spell, followed shortly by Commissioner Gordon, and when Batman himself is tricked into taking the drug, Tut's plan to control all of Gotham City by tainting the water supply seems close to succeeding.
