 Judy Jetson stars in this full length cartoon. She writes a song, she then gives it to rock and roll star, hoping that he will perform it. However, a woman named Felonia, who hates music and would like to obliterate it, needs a rare element to do. Now she gives her two bumbling errand boys a coded message to deliver to her general so that he can get it, but the two guys bumped into the rock star and they got Judy s song and the rock star has the message. Now the general goes to the wrong place and gets the wrong thing and the rock star performs what he thinks is Judy s song. And when Felonia hears it, she has the rock star abducted and is also after Judy.
