Expelled from their homes, crammed into cramped cattle wagons. They were imprisoned thousands of kilometers in extreme, inhumane conditions, there where the sky meets the earth. Treated as a hostile anti-Soviet "element," oppressed, humiliated and forced into backbreaking labor for decades. For a long time forgotten even by their own homeland, today they are often perceived by their compatriots as "arrivals from the East." Yet they managed to preserve Polish tradition, faith and dreams of returning to the land of their ancestors. This is the story of the descendants of Polish exiles deported to Kazakhstan - a story of dramatic fates and awaken hopes for a return to their fatherland. Can we, as a society, accept them, understand them, and respect them? Will we be capable to make them feel at home - the home from which they were deprived of for so long? "To Rejoin the Nation", explores a little-known yet profoundly important part of Polish history After the signing of the Treaty of Riga, millions of Poles found themselves in territories occupied by Soviet Russia. Many became victims of NKVD (the interior ministry and secret police of the Soviet Union) repression and those who managed to survive were brutally deported deep into the Soviet Union. They were sent to labor camps and collective farms in Kazakhstan, where for decades they were forced into hard, slave labor. Everything was taken from them - their homes, freedom, dignity, and often even their faith and hope. The film was shot in Poland and Kazakhstan.
