A Farewell to Hemingway(2008)

Bulgaria, the night of October 18, 1922. A rampageous young man - an American, is forced to get off the Orient Express at a small station. The chief of the railway station and his daughter are quite unwilling to put up the stranger. Gradually, the American wins their trust. When the father understands that his daughter has decided to go away to Paris with the American, he makes a potion to sedate him and gets him on a train on the sly. In the morning all that has left from the guest is a piece of paper, which reads "Ernest Hemingway".
