On the eve of the elections, Katerina comes to Athens from the countryside to vote, disrupting the daily life of her nineteen-year-old son Michalis. From her old friend Marika, she learns that Michalis has dropped out of the university he attends and is preparing to leave for America, leaving behind his pregnant girlfriend, Fani.

In her attempt to change Michalis's mind, she confronts him. He threatens her that he will commit suicide with a gun that he found in a mysterious illegal situation, which allegedly involves Fani's sixteen-year-old brother, Giannoukos. Everything will happen quickly under the threat of a gun that will never fire, but will change the lives of the characters forever.

One of the most important works of contemporary Greek dramaturgy, Loula Anagnostaki's The Sound of the Gun, which became the swan song of the greatest Greek director, Karolos Koun, and has since been repeatedly staged in many theaters across the country, presents against the backdrop of the festive pre-election atmosphere the dead ends faced by young people, mocks the conventional bond of marriage, and explores through suggestive writing and sparse episodes the existential anxiety and the state of mind of our times.
