After what is believed to be a meteor flies overhead, Maple Street experiences a total power failure. Pete Van Horn leaves to find what is going on. Tommy, a reader of sci-fi, says human- looking aliens have infiltrated Maple Street. No one takes this seriously until Mr. Goodman's car cranks for a few seconds. Suspicion falls on him, made stronger by a neighbor's memory of seeing him looking up at the stars at night. Everyone begins to panic as the evening approaches. When a mysterious figure walks towards them in the dark, Charlie Farnsworth takes a neighbor's rifle and fires. The mysterious figure turns out to be the returning Pete Van Horn. Charlie is then accused of being the alien, then Tommy, then total madness breaks out. As various house lights flash on and off, rioting breaks out. Two nearby aliens watch these events. One tells the other that by manipulating electricity, it is easy to turn neighbor against neighbor. Maple Street is only the beginning.
