You've so well taken me through it.
Hanna at 16,finding herself in a hunting ground, for meat with dad, realizes she is also a prisoner,and she wisely escapes.

Am in love with movies of young wise stars who struggle and overcome systems, yet not even because of having unique abilities.

This reminds me of the maze runner, where young boys were detained in a complicated system for long, but finally wisely broke out.
Thanks.
