What Is Polytechnique About?

The premise of Polytechnique in 333 words, with nothing given away. The full story follows below.

In the early winter of 1989, the campus of Polytechnique Montréal hums with the focused energy of its engineering cohort. The film opens on bright lecture halls, the clatter of keyboards, and the quiet determination of a group of women who have chosen a field still dominated by men. Their studies are interwoven with everyday moments—coffee breaks, late‑night study sessions, and the subtle rituals that bind them together. The atmosphere is rendered with a spare, almost clinical aesthetic that lets the ordinary texture of university life breathe, while an undercurrent of unease hints that the world outside the classroom may not share the same respect for their ambition.

Among the students, Jean‑François navigates his own path, balancing the expectations of his peers with a lingering sense of responsibility. Valérie, disciplined and precise, carries the weight of future professional symbols, while Stéphanie brings a quiet resilience that steadies those around her. Their interactions are marked by camaraderie, gentle rivalry, and the shared hope of forging a place in a demanding discipline. The relationships they nurture feel both intimate and fragile, underscored by the subtle pressures of a society that often questions their presence in the lab.

The film’s tone is unflinching and contemplative, opting for a restrained visual language that mirrors the stark realities of its setting. Long takes linger on empty corridors and echoing lecture rooms, allowing the audience to feel the stillness that can precede disruption. A muted palette and deliberate sound design amplify the feeling that something unspoken lies just beyond the periphery of daily routine, inviting viewers to sense the tension without spelling it out.

Through its careful focus on character, environment, and the quiet moments that define student life, the story asks what it means to belong in a space that can be both empowering and precarious. It leaves the audience with a lingering impression of a world on the cusp of change, where the promise of tomorrow is shadowed by forces that are, for now, only hinted at.

Spoilers ahead

Valérie, Karine Vanasse, and Stéphanie, Evelyne Brochu, are engineering students at Polytechnique Montreal who find themselves caught in a sudden, devastating attack. A troubled young man, Maxim Gaudette, arrives with a Ruger Mini-14, leaves a message for his mother, and enters a classroom in the middle of a lecture. He orders the men to leave and the women to stay, then fires a shot into the ceiling to prove he is serious. He declares his hatred of feminists, and although the women deny being feminists, he shoots at them, killing some and wounding others. He moves through the building—along the halls and into the cafeteria—before continuing to target women in his path.

Jean-François, a male student who had been ordered to evacuate, defies the order and returns in a bid to intervene or assist the victims, hoping to slow the onslaught or save lives. The survivors, Valérie and Stéphanie, work to stay hidden as the threat lingers, with Valérie clinging to a fragile calm and Stéphanie hoping to outlast the danger. Stéphanie is gravely injured in the chaos, and the damage of the day becomes tragically personal for everyone involved.

The killer presses on to another classroom, where he kills a female lecturer before ending his own life, his final act leaving a smear of blood among the victims. The school awaits the aftermath in silence, and the community begins to reckon with what happened, and with the choices made in those crucial moments.

In the days and weeks that follow, the memory of the day continues to haunt those who survived. Jean-François, overwhelmed by guilt for leaving the room and for not doing more to intervene, dies by carbon monoxide poisoning, a private tragedy that underscores the film’s quiet, unflinching examination of responsibility and grief. Valérie, meanwhile, carries the weight of survival into a new phase of life—wearing the Iron Ring as a reminder of her profession and her identity—then learns she is pregnant. She contemplates her future and what she might tell her child, resolving to affirm that the world belongs to her, no matter the challenges ahead, a testament to resilience in the wake of catastrophe.
