Miss Bala (2012)

In Mexico's border city of Baja, Laura (Stephanie Sigman) wants to enter a beauty pageant. The night before the audition, she inadvertently witnesses an armed invasion that leaves dozens dead. As the only living witness to the massacre, she soon finds that telling her story to the police was the wrong thing to do when she's delivered into the hands of a gang boss (Noe Hernandez).
