- A journalist uncovers a link between a series of stories which is leading to a further crime which only they can stop.
- A Police Officer finds a link between a series of unsolved cases and tries to stop further attacks.
- Man in an accident tries to figure out what happened, while avoiding a mystery gang. Events preluding the accident would be told in flashbacks.
- A member of a secret organisation tries to overthrow their corrupt leaders after being framed for killing their fellow men.
Of these 3 of the 4 are involving a conspiracy of some kind, while the fourth (idea number 3) looks more into the mind, in a Memento style. Idea's 1, 2 and 4 could be mixed, for instance it could be a Journalist who finds the link between the unsolved cases, which leads of the secret organisation. These fit in with the findings from all aspects of my audience research, as Conspiracy Thrillers are one of the more popular sub-genre's, and often feature protagonists/characters with a hidden past (one of the things from my audience research), and would focus on the narrative. There may be hints of action, but little to no Special Effects, as this is what my audience expect from Thriller films.
