RE: A god-fearing headmistress explores ungodly means to stage the suicide of a student in order to help him cut off from his toxic parents.
I read your previous logline and this one. As a result, I would say, how the logline should be written depends on what the audience knows and when they know it…
Does the audience know the headmistress helps the kid fake his death? Or is it a big reveal?
If the audience knows from the start the headmistress is helping the kid fake his death then this is good.
If the audience is in the dark about the headmistresses plan, then you are back at square one because a logline never gives away the big reveal.
