You’ve posted your film description and tagline, but the Logline is absent. The three mandatory components (we believe) necessary for a great logline are:
? the story?s first major event or ?Inciting Incident?
? the hero?s function or role in the story
? the hero?s goal or main action in the story
After which your logline must raise this one question only — “will the hero achieve his goal?”
While your logline raises many, including — Which of the three is your protagonist? What incites them to join the resistance? & As a result, what becomes his/her objective goal?
Loglines with a fiction premise such as this, benefit from establishing the setting prior to the event-role-goal, such as — “Under human subjugation, when the mythical specie of Faunus are faced with jarring immorality, a young faun with his two close friends must ____[reach this goal/do this action]…

Although optional, It benefits greatly from an inciting incident which implies 1) the hero?s weakness/flaw (e.g. headstrong, timid, solitary, cocky, depressed), 2) an obstacle(s) and/or the Antagonist & 3) the stakes
