As the Mercury Men approach, Yaeger sets up a barricade and entrusts Borman with his pistol, which he finally finds the courage to use after cowering through a few salvos. The sentries seemingly retreat, but then more appear, and the attack intensifies, with Yaeger and the glowing invaders exchanging fire. Meanwhile, Yaeger rushes to make the final calculations for his alteration of the gravity engine. He flips a switch, but rather than reversing, the engine simply shuts down. It needs power, but as Yaeger goes to retrieve his pistol from Borman, he's gunned down by a lightning blast from one of the Mercury Men. Borman finds the courage to counterattack, but the pistol is now empty. Left with no alternative, Borman runs, but finds only a dead end. The moon is getting dangerously close to the Earth, now. Borman, seemingly hiding behind a pole, comes under fire again...but it was actually a clever ploy, as the aliens' lightning actually powers the gravity engine, causing its effect to reverse. As the moon drifts back into place, Borman flees another Mercury Men attack, and is saved as agents of the League appear! They take care of Yaeger and wrap things up, as Borman returns to his office, where all returns to normal. (thetvdb.com)
