The film was in color. The main actor was White. He went to Europe to meet a woman, some confusion about whether she was supposed to be a connection or not. Don't know if he was mistaken for an agent or an actual one; leaning toward the latter. There was an underlying romance. There was a scene in which he put something in/took something out of the sole of his shoe, I'm not sure what but it was cool to me at the time. This was in a restaurant.
The family was put in front of a firing squad and began singing; we see them get shot as they sing. I'm not sure if they were Jewish or Italian. Later, we see his lover get brought out and shot. He is in a cell that has a window to the execution area.
He escapes. The final scene is him walking in a park somewhere, meeting someone.
