Peeping Tom (1960)

Loner Mark Lewis works at a film studio during the day and, at night, takes racy photographs of women. Also he's 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.

Peeping Tom keeps every mind human — it fights its subject at zero distance. The story fights on E8/E9 of the E0–E14 reality ladder.
