George's car breaks down and he has to ride a space bus back home. There he meets a scientist with a new invention called Replayola, a device that enables its user to change any bad moments of one's life into good ones. George buys the device from him and immediately puts it to good use. He's able to be a good public speaker at the neighborhood meeting, then buys worthless stock, only to make it valuable, making the Jetsons rich. He's then able to avert disaster at a fundraiser which will lead to a run for President. Meanwhile, Jane's old boyfriend Funky Finkston comes into the picture and begins to make George more jealous as he climbs to power. He decides to use Replayola to erase the moment Funky and Jane kissed. But this results in disaster as this moment occured on George's wedding day, which now never happened. George is now a bachelor with no children and he tries to get Jane back. But now she's married to Funky and all hope is lost unless he returns to the point when he met the scientist on the spacebus and is willing to give up his power and riches to get thing back to the way they were.
