Apt Pupil (1998)

In 1984, Todd Bowden, a brilliant high school student with a deep fascination for the history of Nazism, notices an elderly neighbor whose appearance seems to match Kurt Dussander, a wanted Nazi war criminal. After a month of suspicion, Todd knocks on the man’s door and uses what he believes he has discovered to blackmail him, drawing them into a disturbing connection built on secrets and fear.
