Here are two slightly different attempts.

————————————————–

“When he receives a message that his mother is fatally ill, a loner with an abusive childhood reluctantly returns home to take care of his mother while congfronting the ghosts from his past.”

“When he receives a message that his mother is fatally ill, a loner with an abusive childhood reluctantly returns home to take care of his mother while also having to deal with his drunk and abusive father”

Okay, this probably isn’t quite right, but here is a go based on what you said your story was about. It might still need some changes though, so it is more of an example than a finished logline

———————————————————–

“When her special education institution closes, a student with cerebral palsy fights against her parents and teachers, to be admitted to public school in order to have a normal senior year.”

What exactly is the lead character’s goal?

Is there a ‘bad guy’?

Is the closure just a ‘rumor’ or is the school going to close unless the lead does something?

I think all the elements are there, and I can picture the story in my head.

I do wonder what the attacker wants revenge for, what did the granddaughter to do the attacker?

This is an interesting situation, but what is the lead character’s goal, and what is standing in the way of that goal?

I wouldn’t completely abandon your last logline, It was catchy, Instead, I would just add a couple of things to it.

The main thing your first logline was missing is what set the story in motion. Why does she come off the wall now, what happens?

Here is an example of an event that sets her course in motion, obviously yours would be different this is just an example:

“When everyone forgets her birthday, a wallflower comes off the wall, and vows to make the world her stage”

Second, you were missing a specific goal, what does, “Make the world her stage” look like on screen? Is it dating the ‘hot’ guy? Is it letting it all out and telling everyone the brutal truth? How does she make the word her stage?

In other words, what is her specific goal?

Why her? (Just curious)

I’m just wondering why she doesn’t do like a bank teller who is being robbed and just tell them, take what you want. After all the drugs can be replaced but human lives can’t.

I think you need the gang to take someone she cares about, hostage. That way she can’t just walk away but must do something.

Also, you need to get rid of her phone. At the beginning of the story, you should show her phone battery on empty and she forgot her phone charger. Just make it a quick ten-second scene where she realizes she forgot her charger but she is late so she can’t go back home to get it. Otherwise, people will wonder why she just doesn’t call the cops.

Anyway, good luck with this, it sounds interesting.

Is this script written?

Or are you just fleshing out the idea before you begin writing the story?

I only ask because if the story has not been written I would suggest that as a story point: the princess hates werewolves.

In other words, she believes that werewolves are responsible for the attack on her village but the lead character knows it’s the evil knight.

At first, she captures the lead character and doesn’t believe he is innocent she believes he attacked her village, but after a while, they reluctantly team up in order to take down the actual bad guy who attacked both villages.

This version is better than the first version by far.

Also, mikepedley85’s suggestion is solid.

Why now?

If the slaughter happened when the werewolf was a child, why is he getting his revenge at this particular moment? Why not go after the mysterious knight last year? Why not go after the mysterious knight next year?

What happened that causes the lead character to take action and get justice right now?

Also, you can drop the part about, “trying to follow in his ancestors’ footsteps” because it distracts the reader with a second goal. The main goal seems to be to get justice for his slaughtered village. So you don’t need the second goal of following in his ancestor’s footsteps.

anyway, this sounds like an interesting story, good luck with this.
