On Maple Street, somewhere in America, we are introduced to the residents. They are talking with each other, kids are eating (typical neighbor hood). Suddenly a meteor like light streaks across the sky ,and all the power goes out.
Tommy tells the neighbors that the power-out is being caused by aliens from outer space. He says they turned the power out so the residents can't leave. He also says that aliens are living among them hidden as a family.
When Les Goodman's car starts by itself the people start suspecting him to be an alien. This leads to other accusations about his odd tenency to wake up and look at the sky. The people then choose to stake out and watch him that night. When Steve goes over to talk to Les people start accusing him of being an alien.
A silloute in the darkness suddenly appears on Maple Street. Don grabs his shotgun but Steve convinces him not to use it. Then Charlie gets a hold of it and shots what he thinks is an alien. It is actually just Pete Van Horn and Charlie is blammed for his death.
The residents start throwing rocks at Charlie and his house. Then Charlie makes the accusation that the alien is Tommy, causing his mom to have to run with him. Also during this time every neighbor is blaming each other and total chaos has struck the neighborhood
The aliens had been planning this the whole time. They knew that if they took the power out the neighborhood, people would blame and destroy each other. They are planning to take over the world and just like they did to Maple Street.
