The story takes place on Maple Street in a typical small town in America. On Maple Street, the residents see a flash of light, an believe it to be a meteor. The flash of light seems to stop everything from working; cars, telephones, and radios.
The conflict in the story starts with Tommy and his mysterious explanation. He stated to all the neighbors a story that instilled fear in all the neighbors. Tommy told Steve not to leave with Charlie because "they" didn't want them to leave. This left them in dispair.
One of the first important scene for the rising action is when all the neighbors blame Les Goodman to be the monster because his car engine kept turning on and off. He then called the neighbors sick, and just because he has insomnia doesn't make him a criminal.
The second event leading up to the climax is another blame, but instead of of Les Goodman, they blamed Steve, the one person who was trying to create peace. They choose to blame Steve only because he wants Charlie to stay our of it. They also mentioned that he was making a radio in his basement and he never told them about it.
The climax of Monsters are Due on Maple Street is a horrifying scene. Pete van Horn, the innocent man who only went to see if the power was out on the other street. When he comes back to Maple Street as a figure in the dark, Charlie as well as everyone else were terrified that he was a monster. Charlie pulled the trigger, and killed Pete Van Horn.
As the story comes to it's end, lights flicker in all the houses on the curiously chaotic street, everyone puts the blame on each other, and everyone goes crazy. Meanwhile, its nighttime and two mysterious figures look down at this street and explain that they are the aliens and the real monster is themselves turning against each other.
