The beginning of 1945, Poland. In a newly liberated country, the Communist Security Service is annihilating its enemies under the guise of punishing "national traitors." They organize a labor camp for Germans, Silesians and Poles, on the site of a former Nazi concentration camp called Zgoda / Reconciliation. Franek, who is in love with the Polish prisoner Anna, goes to work as a warder in the camp to save her. He does not know that one of the prisoners - Erwin, his German friend, also loved this girl for a long time. Franek joins the communists in the illusory hope of outsmarting the system.
