Peeping Tom

Mark (Karlheinz Böhm) is a photographer who loves photography and carries a handheld camera left to him by his father. A serial murder case caused panic in the city. The victims were all women. When they died, their faces were full of expressions of extreme fear, and the dignified Mark was the real culprit who committed these horrific crimes. It turns out that Mark's father is a psychologist who studies children's fear. As his experimental subject, Mark has been surrounded by all kinds of sudden scares since he was a child. Such long-term fear and depression have led to his distorted personality and become the trigger of all tragedies. By chance, Mark was attracted by the beauty of his neighbor Helen (Anna Massey). Just when he was about to attack Helen, he hesitated. Helen's innocence and beauty temporarily healed Mark's childhood trauma, but the often raging madness made him fall into self-entanglement with his nature. Mark's successive crimes attracted the attention of the police. When he was arrested, the desperate Mark chose to self-destruct.
