In Maple Street, a loud sound and a flash of light goes across the sky. It starts to turn off all the electricity and power. Steve and Charlie notices the flash of light and the neighborhood starts to panic.
As Steve goes out of the street to see what is happening, Tommy warns him that it could be dangerous. Tommy tells them about a book and movie that shows aliens invading Earth, and that could be happening now. Steve and Charlie listens to Tommy and suspicion grows between the neighborhood.
Suddenly Les Goodmen's car turns on, and Sally, Don, and Charlie start to accuse him as an alien. Charlie starts to accuse Les from acting weirder than the others, as he is afraid. Steve was still confused and tried to think of a reason why it turned on to calm down the mob.
Don Martin mentions a secret radio that Steve works on for many nights. Charlie starts to accuse Steve as it starts to make a mob towards him. Myra, Steve's wife, starts to defend him because she told everybody about it, but the radio is just a radio set to play with. Steve refuses to let the people search his house.
Pete Van Horn when out of the neighborhood to see if they were having the same electrical problems. He eventually came back during night time, and the neighborhood only saw a shadowy figure. Charlie thought Pete was one of the invading aliens, so he killed him with a gun. Everyone started to accuse Charlie because he was quick to kill him.
The shadowy figures were in the flying space ship that went by Maple Street. They started to turn the electricity on and off again. One shadowy figure said that the citizens of the street will start to accuse and fight one another from any evidence. They started to repeat this process on other streets similar to that one.
