An unsettling experimental documentary that imagines a guided visit through a national mental hospital, The Torment Zone (La Región del Tormento) delves into the mechanisms of psychiatric and legal control that define the treatment of madness. Blending archival textures, hand-drawn animation, and documentary fragments, Marcello Mercado constructs a surreal and claustrophobic environment where medical and judicial discourses intertwine. The result is both a political and psychological reflection on the boundaries of reason and confinement—an early work that anticipates Mercado’s later investigations into biopower, institutional violence, and the anatomy of control.
