1989, Montreal. A man stalks the halls of Polytechnique Montréal with one goal in mind: to kill as many women as possible. A somber, meticulous pace belies the film’s urgent message: in empathy, there is hope. A searing work, more relevant than ever, the third feature from Denis Villeneuve is a quietly provocative dramatization of a horrific tragedy and marks a stark departure from the director’s earlier surrealistic works.
