During World War II, a woman aboard a railroad car full of deportees slips French railway worker Julien a note with an address and a simple message: "I am alive, and I love you," and he decides to track down the intended recipients. When he finds the woman's Jewish family, he is inspired to do what he can to protect them from the Nazi atrocities.
