A convent in Venezuela, 1929: on demand of her parents the young Maria is received as a nun in the order. The strict rules of the convent and the approaches of the other sisters won't be her only problems soon. Because since a fresco is uncovered behind the walls of the chapel, an unholy force seems to find its way into the convent. Even the son of the lord himself comes down from the cross to push the nuns into a swirl of lust and occult rituals.
