[4] Stepan "Chicha" Chichulin, a tenor in a provincial military choir, surprises a crowd of angry protesters by unleashing a powerful bass voice while attempting to escape them during a rally.
However, his impressive bass talent doesn’t stay hidden for long, and soon the choir's artistic director dismisses him, believing such a voice deserves a larger stage.
As Chicha and his partner achieve financial success, he performs at restaurants, imitating artists like Adriano Celentano, and gradually drifts from his "bass-only" commitment.
In a turn of events, Chicha is forced to sing in a high-pitched voice to entertain a notorious mobster, now immobilized and encased in plaster at a hospital, by performing songs from the band Laskovy May.
Upon her return from Moscow, Chicha’s wife reveals that the recordings of his bass performances have garnered interest from a small experimental opera theater.
