The early 1950s, Poland under the Stalinist regime. Tonia Dziwisz travels with the band around the country, giving performances for urban and rural proletariat. One evening, shortly after an argument with her husband Konstanty, Tonia is made drunk in the restaurant by two men and then taken to jail. The secret police demands that she give testimony incriminating her colleague. A long-lasting, hopeless interrogation begins.
Interrogation is a shocking study of a human faced with ruthless Stalinist tyranny. The film-legend, classified by the authorities as the most anti-communist film of the communist regime, was the direct cause of the dissolution of Andrzej Wajda's Zespół Filmowy X. A year after the film was shot Ryszard Bugajski left Poland. The premiere took place not until 1989, at the Polish Film Festival in Gdynia.
