Punky and Cherie enter a radio scriptwriting contest sponsored by a local radio station that has just changed its format from rock music to radio stories, and Punky, Cherie, and Margaux hope to win the grand prize trip to Disneyland, unless their opponents Garth Goobler and Grant Goobler, the self centered sons of a radio star, stand in their way. Punky, Cherie, and Margaux outdo the Goobler brothers and win the contest.
