When a senior police officer who does everything by the book sees her daughter being stabbed to death, what side of the law will she now be on!

Hi Karel

Many thanks for taking the time to offer some positive feedback on my logline and an understanding of the crux of the story. and it does need a rethink.

As we speak am busy on rewriting the logline and a four page treatment of the screenplay.

Thanks again.

Paul,

Hi Sharkeatingman,

Many thanks for taking the time to offer some positive feedback on my logline, and it does need rewriting. However, the 'everything by the book' phrase cannot be replaced by words such as (undeviating, dependable, assiduous, disciplined, conventional, dutiful, reverential, devoted, meticulous, detailed, particular, specific or especial)as these dont give the same meaning.

Thanks again.

This is a good character setup. The 'does everything by the book' could be a thematic setup, as in some of my favorite movies: Touch of Evil and The Untouchables.

sees her daughter being stabbed to death,
Quite disturbing inciting incident. One could argue it may be too strong as the audience may not expect her to recover from this in the course of the movie. Often this type of event causes the main character's 'wound', like Don Cobb in Inception who saw his wife die. In this case, it actually predates the start of the movie and it doesn't happen on screen. The movie's inciting incident is something else, happening somewhere in Act One.

what side of the law will she now be on!
I'm expecting that after the loss of the daughter, a new case starts and the officer's morality is tested. Will she still play it by the book?

Similarly, in The Untouchables, Eliot Ness plays it by the book only to see himself portrayed in the newspaper as an idiot. Will he continue play by the book in order to capture Capone? Here we have a clear objective and the question is whether he will stick to his 'old' morality in the course of pursuing this goal.

What is lacking in your logline is that new goal, the new case that will test your main character's morality. This new goal will constitute most of the story, i.e. the 2nd Act through to the 3rd Act climax.
