An insecure prison doctor cooks up misfortune for inmates when she discovers a desire to care for burn victims.
This sounds like an intresting concept and you have a good main character, but to make it a better logline it needs three things:
1. An inciting incident: what happens that makes her discover that desire? Whats gets the story starting?
2. A clear goal for the main character.
3. A main action: what must the doctor do to reach her goal?
Hope it helped! 🙂
