Bugs is getting ready to conduct "The Warner Bros. Symphony Orchestra" (supposedly in concert at the Hollywood Bowl) fancily. When he finishes his elaborate preparation, he starts to conduct. However, several problems plague Bugs' conduction, notably a bothersome Fly, and some awkward cuffs that keep falling off. Bugs attempts to kill the fly, crashing into the orchestra and the instruments as he does so. As the music comes to a stop, Bugs bows for the crowd, and instead of applause, hears only silence. Bugs looks around to see that the seats are empty, though he does hear some faint clapping - coming from the fly. Bugs bows to the fly.
Though Mel Blanc was credited for the voices of all characters, there is no dialogue in the short. The only vocal effects made are when an audience member is heard coughing, and Bugs makes a 'shooshing' noise. This is the only Bugs Bunny cartoon (other than "A Corny Concerto") where Bugs is silent (apart from the 'shoosh').
Although not a direct remake, the cartoon is similar in concept to "Rhapsody Rabbit", where it features Bugs as a concert musician (in this case as an orchestra conductor) upstaged by a pesky little creature (in this case, a fly). The fly from this cartoon, as well as Cecil Turtle, the Gremlin from "Falling Hare", and the unnamed mouse from "Rhapsody Rabbit" are the very few characters who managed to outsmart Bugs.
