About
Servais Mont, a freelance photographer who works taking compromising photos, gets fascinated by Nadine Chevalier, a tormented low-budget movie actress married to an eccentric film photo collector.
An obsession with voyeurism transforms a photographer's lens into a tool for both destruction and desperate longing. This slow-burn portrait of a crumbling marriage feels less like a standard romance and more like a haunting study of how we consume the people we claim to love.
