Scenario 2

Our second scenario is of a dark room, with very low level lighting, the audience can just about make out a bedroom scene with a bed in the centre. Using a point of view shot the audience can see this (possibly with heavy breathing heard as it is a POV shot). Non diagetic tense music will be playing in the background to arouse tension.
The camera is going to be used as if seeing the scene from the first person, then with a second shot to show the second person in the room and it will show them hiding when the phone rings, suspicion will be high at this point as they will not know why there is someone crouching at the end of the bed and what they are planning on doing.
The tense music will suddenly stop when the phone on the bedside table lights up and starts to ring, the suspect who the POV shot was from will duck down behind the end of the bed. This is to shock the audience as they will be wondering what is going to happen because of the music and the darkness and then when the phone goes off it causes shock.
