The theme of the teleplay "The Monsters are Due on Maple Street" narrated by Rod Serling is to not be too quick to judge, because usually you're not correct. The people on Maple Street assumed that one person after another was the monster, because they judged too fast. However, while they were blaming people, they didn't know that they were the monsters themselves.
The citizens of Maple Street are just regular people, they're friendly, people are roaming the streets.They live on an average American street.
Out of nowhere, a so-thought meteor crashed into their neighborhood. Everyone was worried, afraid of what this meteor could be.
Although all the citizens were freaking out, a 14 year old boy knew what it was; an alien spaceship, and the aliens were disguised as humans. All the power went out, every battery-operated thing went out, even cars weren't working. Pete VanHorn went to the next neighborhood to investigate.
Les Goodman tries to get his car started but it won't start. He walks away for a few seconds, and it suddenly turns on. This gets everyone riled up. They start accusing Les of being a monster since only his car works.
More and more people are being blamed for being a monster, including the 14 year old. However, none of them were.
Charlie sees a figure that has to be a monster, so he shoots his gun and hits the figure. As they come closer, than realize it was just Pete. Little did they know that two figures lurked in the shadows, watching at how a little bit of mishaps can change people.
