From there, the film follows Laura’s progressive decay. It is a relentless, observational horror show. As her flesh begins to slough off, her social and emotional structures disintegrate completely. Antoine, horrified by her state, abandons her, and her friends drift away. The film's second half is a masterclass in atmosphere and practical effects, as we watch Laura, now almost entirely alone, navigate her apartment as her body literally falls apart. The line between her rotting body and her decaying emotional state blurs completely, culminating in a dreamlike, hallucinatory finale where she becomes a living corpse, a piece of human art existing only in the decaying space of her own mind.
