Conventions within the film is the dead body which is an enigma

Camera Techniques: High angle shot, shot reverse shot (dead body vs protagonist) and flashbacks

Editing: Mostly straight cuts, simple and do not complicate or make the transition from one scene to another look worthless.

Sound: The music creates an atmosphere of sadness, the dialogue from a phone call causes tension and suspense (mystery)

Mis-En Scene: There is a graphic match used from the present scene to a flashback by using the victims (dead body) bangles
