Red Rooms is a slow-burn thriller that follows Kelly-Anne (Juliette Gariépy) as she gets drawn into the case of a suspected serial killer in Montreal. She religiously attends every trial, even camping outside the courthouse to secure a seat, and eventually neglects work for it. Her obsession—maybe more than the case itself—is the film’s true mystery. Why is she so invested? What does she have at stake? Does she know the killer? Is she for or against his incarceration? The entirety of Montreal is split between his innocence, and yet the film doesn’t let us in on what Kelly-Anne thinks. This can feel frustrating if you’re used to the instant gratification of fast-paced thrillers, but Red Rooms’ payoff is rewarding. With every passing scene, Gariépy turns increasingly unpredictable which, in turn, makes for an increasingly unsettling watch.

How Gariépy can convey so much by saying so little is marvelous.
