Great logline and a great concept.
The success will depend on what the 'sinister nature' is. If a specific major event pushes her over the edge to take action, perhaps include this in the logline.
Another aspect I always like to see is the character jouney. What does our hero learn? Perhaps she believed in the regulation of private life at the beginning and no longer at the end. Then what made her join the committee? Did anything in particular happen in her past that made her believe in the 'radical parental exams'?
Some things to consider...
