Tony and Janina Wasilewski were model immigrants: hardworking, law-abiding, and beaming with freshly minted patriotism for the U.S. Then Janina, who came to Illinois claiming refugee status during Poland’s communist regime, was abruptly deported in 2007, taking the couple’s six-year-old son back home with her. Coproduced by Chicago’s venerable Kartemquin Films, this moving documentary uses the Wasilewskis’ plight as a window onto our absurdly byzantine and arbitrary immigration controls, which tear apart hundreds of thousands of comparably blameless families every year. Director Ruth Leitman deftly balances heartbreaking drama and muckraking journalism. In English and subtitled Polish.
