When a space alien's fascination with Earthlings gets the better of him, he breaks one of his planet's laws and speeds off to visit the blue planet. Once there the alien (Jerry Lewis) encounters a nice family who kindly take him in. The father is a news commentator. Ironically, just prior to meeting the visitor, he had just aired a piece in which he derided all notions of extraterrestrial visits. In exchange for having them teach him about human ways, he uses his many fantastic powers to help them.
