Artur Sokolov, grew up in a Russian village which, several months a year, is only accessible by boat due to its geographical location, at the edge of a Siberian river. He returns there, after training in documentary writing, and shoots the images that will make up this film. Phalène owes its title to butterflies famous for their ability to adapt to their chromatic environment (they take on the color of tree bark), which are intoxicated by the neon light at night, as shown in a plan of the movie ; their ecological skill, and their optical sensitivity are very much in the image of those evidenced by this shot in particular (technically remarkable, and poetically striking) and the film as a whole.
