The opening sequence of "Seven" uses fast cuts between shots of various objects like books, scissors, and paper to portray a person searching for something important without revealing what. This lack of context and continuity creates confusion and questions for the viewer about who this person is and what they are investigating. Eerie non-diegetic sounds and tense music further build suspense without providing answers. Through vague mise-en-scene and tight camera work that does not show the full context, key details are withheld, heightening the mystery of the sequence.
