“The Gray Cloud of Death!”
After losing contact with the first mission to Venus, a second ship is launched to investigate. They find the lost ship floating in space. The crew of the Venus-2 board it, and find that all organic matter (flesh, rubber, plastic) has been eaten away. They find a hastily written note, warning them about a gray fog that attacked the first ship, causing the devastation. Before they can return to their own ship, the searchers see the fog moving to attack it, and the captain orders the remaining crew to flee back to Earth. The search party then watches resignedly as the fog turns towards them.
“The Martian Monster”
Freddy has a vivid imagination, so when he hears a voice in from the woods claiming to be a Martian, he's ready to believe it. When he tells his Dad (Sam), step-Mom (Jean) and step-Uncle (Ben), though, they accuse him of lying. Then, the Martian tells Freddy that Sam loves Jean more than he loves Freddy and encourages Freddy to murder his Dad. Sadly, the "Martian" was really Ben, fulfilling a plan to get Sam's money (Jean was in on the plan). But, while celebrating their ill-got wealth, Jean and Ben get a nasty surprise: it turns out there WAS a real Martian. And, it's not happy with them.

After a long voyage, they find a planet that has all the necessities they need to survive, and they resolve to build a new society, free from war and strife. But, while bringing their ship in for a landing, they are shot down and killed. By the US Air Force.
“The Slave of Evil!”
A man awakens to find himself on a lab table, with two scientists looking down at him. They tell him his name is Peter and they give him an assignment to kill another man. Peter commits the murder, unquestioningly. Peter is then given a similarly amnesiac companion for another killing, but something goes wrong. His companion is shot, but there's no blood! When Peter arrives back at the lab, he overhears the scientists boasting that their new creations would allow them to rule the world. Peter realizes he's nothing more than a robot, and that moment of insight prompts him to kill his creators.
