Kids at a summer camp find the camp's old radio station and brings it back to life with the help of the camp director, who used to be the DJ for the station when he was a kid.
Addy, DJ PJ, and the rest of the gang are preparing for the big Jamboree. But there is a problem with the power to the radio station so Brian goes to work. While they wait on the DJ booth to get repaired, the silly kids reflect on the fun they had this summer. And a special guest joins the group to close out their time together.
