The members of a summer theater group get mixed up with spies and murder.

The shooting and murder of two guest stars at the Shady Ridge Summer Theatre, operated by Joan Barry, threatens to close the musical "Fun For All." To bolster the show, Joan induces Bill Edwards, who shares joint ownership with her, of the farm the theatre is located on, and Sheriff McKenzie, to hire the Jolly Jesters. They steal the show and, along the way, uncover a spy ring and a bullet-shooting clarinet.—Les Adams <[email protected]>
