The Flash stops a speeding car. Three men step out of the car, and challenge the Flash to a race. All are under hypnosis, and state they will die if the Flash does not race them. At the library, the Flash learns the identity of each man. The race car driver, Don Blake, the speed boat captain, Frank Hobbs, and the test pilot, John Quint. Each man holds a speed record with his chosen conveyance. The Flash meets Blake on the salt flats outside Central City. Impossibly, Blake is able to keep pace with the Flash. Spying an old prospector, dying of thirst, the Flash breaks off from the race.
Using a cactus for a drill, the Flash brings up a fountain from an underground spring. Rejoining the race, a mere second later, the Flash is beaten when Blake suddenly blows past him. Blake vanishes in a burst of light. The Flash meets Hobbs out in the Pacific Ocean. Equally impossibly, Hobbs, too is able to keep pace with the Flash. When their combined wake disrupts the launch of a polaris missile, the Flash breaks from the race to correct the missile's course. Resuming the race almost to the second he diverted, the Flash is amazed when he is beaten again. Hobbs, too, disappears in a burst of light.
Joining Quint, high in the sky, the Flash runs along ice crystals in the clouds to keep pace with Quint. Incredibly, Quint pulls ahead, capturing the Flash in his jet's slipstream. Quint puts his jet into a nosedive, pulling up at the last second, to hurl the Flash into the ground. The Flash vibrates his molecules to incorporeality, so that he passes harmlessly through the ground. Quint disappears in a burst of light, only to reappear, in a deserted concrete bunker, as Doctor Light. Doctor Light has been the Flash's true opponent in each of the three races.
Each of Doctor Light's vehicles were equipped with technology to absorb the Flash's super-speed, allowing Doctor Light to surge ahead in each race. In effect, the Flash was running against his own super-speed. Having collected the Flash's super-speed energy, Doctor Light charges up the entire structure of the bunker, and waits for the Flash to arrive. The Flash races around the bunker, until the pressurized force he's created, destroys the bunker, thwarting Doctor Light's plan to slay the Justice League of America. Unbeknownst to Doctor Light, the Flash outraced Doctor Light back to his bunker, after the final race, and learned of Doctor Light's scheme, and how best to thwart it.
The Green Lantern is attacked by an insect-like alien, Gh=Dro, while recharging his power ring. After a short battle, Gh=Dro steals the power battery, and flees into the woods. The Green Lantern pursues Gh=Dro, losing the alien in the forest. Suddenly, the Green Lantern comes across his power battery. As soon as he reaches for it, Gh=Dro ambushes him. After another short fight, the Green Lantern feigns unconsciousness. Gh=Dro picks up the Green Lantern, but as soon as the pair are close enough to the power battery, the Green Lantern dives for it. After recharging his ring, the Green Lantern blasts Gh=Dro. The alien insect rises up into the sky, eventually reaching escape velocity. With it's propulsion belt fully charged, Gh=Dro heads for home.
