In this musical, former vaudevillian Frank Merriweather (Frank Morgan) manages to get a job on a radio show, doing all 20 voices in a program about a Martian invasion. But his act is so convincing, it starts a panic and gets him fired. Meanwhile, Frank's three ex-wives show up with their grown children and try to set him up for marriage. Frank bonds with daughter Laura (Virginia Grey) and somehow gets his radio show back. Still, he must figure out how to keep an important sponsor on board.
