Screamer In The Brain! At Leila Taylor's apartment. Captain America and Falcon are suddenly overcome with madness and hate. They initially fight but come to their senses. While Falcon restrains a similarly maddened Leila, Cap goes outside into a raging mob. He finds a small device wedged between buildings. Although he again succumbs to the madness, he still destroys the device with his shield, ending the riot. Soon after, a SHIELD agent joins Cap and Falcon and calls the shattered device a "madbomb." He takes them to "Madbomb Control," a secret government base, leading them to the "Panic Course," a lethal obstacle course. Successfully emerging, the heroes meet "Henny," the Secretary of State, who has tested them to confirm they are indeed Cap and Falcon. He tells them of two smaller madbombs, dubbed "Peanut" and "Dumpling" that devastated the towns of Miner's Junction and River City. Then he shows them a photo smuggled out by a SHIELD agent, killed in the process, revealing "Big Daddy," a madbomb big enough to destroy the United States which the government thinks is timed to go off for the Bicentennial.
