When a transgender black woman kills a mentally ill murderer, she is put on trial for life, the jury, who vary from rich to poor to caring to prejudiced,? are caught up in a spiral of grey areas – and a case that exposes the increasingly mad world they live in.

I'm guessing that the transgender description should have some significance or why put it in there. Maybe evidence points to male and transgender person says it's impossible as he/she is a woman. Tell me why that's important in playing out the trial. I agree with above comments in the significance of the victim - he is both mentally ill and a murderer - how does the protagonist fit in? Is it about the the person on trial or the jury? If you want to focus on the jury, the dilemma could be from the perspective of the juror who finds conflict in the story....it depends if we are going to see the story from the trangender person's perspective or the jurors perspective...

I didn't get the whole revenge thing. Unless you changed the logline, it nowhere states that she killed a friend's killer.

Curate your paragraph a bit. Cut words down. Edit. Clean up your syntax. Don't elaborate on how diverse the jury is. It's a jury. Show us that the protagonist is (in) the jury. Don't mislead us to think that it may be the woman.

Write a couple of words about that protagonist. Are they a man or a woman? Are they black? Are they cis or trans? In a case against a black trans woman, a Henry Fonda protagonist would be soooooo patronising.

What do you think is the story hook?

(And yes, drop the "...increasingly mad world...".? A logline should tell the plot, not telegraph the message.)
