The Convent of Hell (Ignacio Noe)

In 1851, the Marianitas Nuns cloister has become a crucible of demonic horror, where a sadistic Mother Superior conducts occult rituals to open a forbidden door. As Vatican investigators arrive, they find the convent awash in sexual torment and blasphemous preparations for a culminating unholy event. All the while, a mysterious 'KISS' countdown ticks toward an unspeakable climax.
