Polytechnique (2009)

A young man prepares his rifle and leaves a message for his mother. He then goes to Polytechnique Montreal, an engineering school, and enters a classroom during class with a rifle. He orders the men to leave and the women to stay. They comply after he shoots into the ceiling to show that he is serious. He tells the women that he hates feminists. Although the women deny being feminists, he shoots at them, killing some and wounding others. He then moves through corridors and the cafeteria, specifically targeting women.

One of the male students is Jean-François, who was ordered to leave the classroom. He does not merely flee, as he returns to try to stop the killer and/or help the victims. Valérie and Stéphanie, two surviving women, play dead thinking the killer has returned, although Stéphanie later dies of her injuries.
