"I'm telling you Fitzhugh, I saw it. It's plain as day.–What is it? What did you see? Tell me, tell me, what you saw.–I saw Earth. Earth! I'm telling you... I saw Earth right through this lens..."
A crazed Giant scientist has developed a type of special binoculars that enable him to see in the dark and capture the little people. Aware of the potentially serious consequences of this, they vow to destroy the invention, but this is not as easy as it first seems as Steve becomes captured by the scientist...
Taking advantage of the fact that the giants have poor night vision, the humans sneak into a lab after disabling the lights, but a scientist spots them with a pair of experimental infra-red goggles. Steve plans to destroy the prototype goggles before more can be made, but during the attempt he and Fitzhugh are captured by the scientist. When Steve claims he can see Earth through the goggles, he piques the scientist's interest, then offers Mark's help in making the goggles more powerful. Fitzhugh is allowed to leave, ostensibly to fetch Mark, but actually to convey a message from Steve ordering the others to blow up the lab with him in it.
