1977. An eighty-year-old father Zieja, the co-founder of the Workers’ Defence Committee, is interrogated by Grosicki, a Security Service officer. Grosicki wants to talk him into collaboration. The priest declines. Grosicki is not giving up. He is very well prepared. He knows all about the priest’s life and wants to use it to earn his trust. The interrogations set the memories from Zieja’s life into motion. Full of dramatic events related to the twentieth-century history of Poland, they become a backdrop against which the priest’s uncompromising moral stance is shown.
