In Claro de luna (Moonlight), the Argentine clown Marcelo Katz goes through both sides of an actor's life: his personal life, his experiences and his difficulties; and his working life, dedicated to the art of clowning.
Both stories feed on each other mutually and allow us to understand some foundations of the lives of the clowns, those comic actors who go up on stage to entertain, excite and establish communication with the public.
