Wildcat is meeting his son, Tom, for the first time. The son knew who his father was. Green Lantern and Flash are called back to JSA HQ because Mr. America has just crashed through the skylight onto their meeting table. Tom tells Wildcat his mother never approached him because they didn't want Wildcat to worry about them. She died from cancer a year ago. Tom has no interest in becoming a costumed hero.

Dr. Mid-Nite checks out Mr. America and pronounces him dead. The stress causes Starman to negate gravity and everything and everyone begins to float. Power Girl gets him under control and everyone crashes back to the ground. He continues to talk nonsense, giving clues to the future. Maxine is upset over Mr. America's death but Stargirl consoles her. Stargirl takes her to a room filled with material and tells her it's time to make her a costume.

Dr. Mid-Nite begins an autopsy on Mr. America and finds something lodged in his lung. The JSA finds out Mr. America's whole family has been killed, eliminating his bloodline.

At the Heywood picnic they are attacked by a group of Nazi villains calling themselves the Fourth Reich. They are under orders from someone to kill all the Heywoods, women and children first. Hawkman arrives on the scene to fight them.

Back at JSA HQ, Starman fixes a formula on a chalkboard that Mr. Terrific has been working on for a year and a half. The theory proposes gravity is a weak signal from a parallel universe. Starman tells him he learned the formula in third grade science. He removes his mask revealing a Starman who looks like the member from the first version of the Legion of Super-Heroes. He says he came here after being trapped somewhere else that was blown to Kingdom Come.
