In the quiet halls of a Montréal university, a weekend academic retreat gathers a circle of scholars, writers, and friends far from the bustle of lecture theatres. The setting feels both cultivated and intimate, a secluded house where books line the walls and the scent of a shared dinner hangs in the air. Over the course of a single night, conversations that begin with lectures on history and philosophy gradually slip into the realm of desire, doubt, and the unspoken rules that hold their lives together.
Dominique St. Arnaud, a history professor known for her sharp commentary on society, arrives with her own mix of intellect and restless curiosity. She is soon joined by Diane, a writer whose latest manuscript probes the contours of happiness, and the pair quickly become the unofficial anchors of the group’s dialogue. Among the men, Rémy—a married professor whose charm masks deeper uncertainties—offers a view into a world where professional respect meets private complexity. His wife, Louise, presents a calm confidence that hints at hidden layers beneath their seemingly open partnership. Claude, openly gay and unflinching in his recounting of personal experiences, brings both levity and an undercurrent of vulnerability, while Pierre rounds out the cohort with his own quietly intense presence.
The retreat’s tone oscillates between witty academic sparring and a simmering, almost tactile tension. As the evening deepens, the group’s polished facades begin to blur, and the line between scholarly debate and personal confession grows thin. The atmosphere is tinged with a restless energy, as each participant balances the desire to maintain decorum with an emerging urge to reveal what lies beneath.
Into this charged mix steps a captivating stranger whose arrival feels both natural and disruptive. Their presence nudges the conversation toward uncharted territory, encouraging an atmosphere where long‑held reservations start to surface. The night becomes a delicate dance of revelation and restraint, promising that the boundaries each character has drawn for themselves may soon be tested in ways they never anticipated.
