"A chilling, methodical look at the psychology of a killer, and a classic work of voyeuristic cinema."
—Rotten Tomatoes
"Here voyeurism itself looks outwards and inwards, confounding perpetrator and victim, filmmaker and viewer, camera and phallic weapon, while observing a pathology as metacinematic as it is psychiatric."
—Little White Lies
"The best movie ever made about the voyeuristic allure of making and watching movies."
—New York Daily News
Loner Mark Lewis works at a film studio during the day and, at night, takes racy photographs of women. He's also making a documentary on fear, which involves recording the reactions of victims as he murders them. He befriends Helen, the daughter of the family living in the apartment below his, and he tells her vaguely about the movie he is making. She sneaks into Mark's apartment to watch it and is horrified by what she sees — especially when Mark catches her!
