The boogie punk rock band Chevalier Surprise invests in a luxurious studio in the heart of the Belgian Ardennes to record Fly de Machiavel. Behind the glass: Marius, an eccentric label artistic director in search of a second "Summer Hit Machine" — the supreme reward for the most contagious hit of the summer — who gets lost in nights haunted by a ghostly Elvis. In the shadows, his alter ego Allan orchestrates the band's downfall, with the complicity of Delphine, a social media nerd with a devastating smile and an even sharper agenda. Glory, sabotage, and the absurd machinery of music and cinema — all served as a dark comedy.
