Sleep Tight, Maria (2015)

A quirky yet insecure 17-year-old girl named Maria V., who’s raised in a Catholic family and school, always masturbates before she goes to sleep. One day, her school arranges a church camp, in which requires all of its students to pray and spend the night together in a secluded place. A few days before the camp, Maria V. finds out that she has to share her room with a fellow student, Maria P. - the smartest, most beautiful and religious girl in her school. To save her pride, Maria V. struggles to fall asleep that night without having to masturbate.
