In this episode, Bart gets a microphone that transmits sound to nearby AM radios. To play a prank on the people of "Springfield", Bart places a radio deep inside a well and uses the microphone to trick the town into thinking a little boy is stuck in it.

Bart becomes trapped in the well and while the town decides to leave him there after finding out about the prank, his father Homer tries to rescue him.
