An outline of the plot

A mystery thriller, about a black mail. The victim is the business man, and a mother who is weak who is a victim as well, and the antagonist, opposite, is the 'Red Caller' a woman in red black mailing the victims. The sim card is the most important prop as well as the telephone box phone, because it is causing the mystery. We are going to set our thriller in London, because it relates to our target audience, because London is were that age group of young adults work etc. The Pleasantville effect will be added, to make the 'Red Caller' the main focus and importance of the opening.
