An actor in a simple blue leotard with tight-fitting hood shows us the light on her derrière. She's playing a male firefly. In a mix of animation and live action, this male blinks and blinks, flying here and there looking for a female with whom to mate. He tells us he must be careful: different fireflies flash different lights, and getting near the wrong one can mean death. He expresses longing: is she the right one? Yes, yes, yes.
