Paper Gag (2020)

Two female students, Max and Sophia, are held in detention to write an essay. An older teacher sleeps with his mouth open at his desk. Noticing this, the two students begin to goof off. They end up throwing paper balls at the teacher, one of which lands in his mouth, causing him to choke, and eventually fall to the ground unconscious. Sophia runs outside, conflicted about what to do about their newly deceased teacher, and Max stays inside and attempts resuscitation.
