chunk: Mark Lewis meets Dora, a prostitute, covertly filming her with a camera hidden under his coat. Shown from the point of view of the camera viewfinder, tension builds as he follows the woman into her home, murders her and later watches the film in his den as the credits roll on the screen.
  Lewis is a member of a film crew who aspires to become a filmmaker himself. He also works part-time photographing soft-porn pin-up pictures of women, sold under the counter. He is a shy, reclusive young man who hardly ever socialises outside of his workplace. He lives in the house of his late father, renting most of it via an agent, while posing as a tenant himself. Helen, a sweet-natured young woman who lives with her blind mother in the flat below his, befriends him out of curiosity after he has been discovered spying on her on her 21st birthday party.
