In rural Louisiana, 11-year-old Sabine's widower father misses Ash Wednesday Mass, so she pushes him to give up drinking for Lent. He breaks his vow, evoking the wrath of the ROUGAROU, a mythical bayou beast who punishes bad Catholics. Now Sabine has to step up to save him from the monster or risk losing her only living parent.

"Best keep to your Lenten vows or Rougarou will get you."
