The cura of Coyoacán, a man of the cloth, finds himself entangled in a dance of desire with a woman who is both devout and debauched. Their trysts are secret, their encounters charged with the electricity of the taboo. She is a contradiction, a sinner who prays for absolution even as she spreads her legs for him. He, a man of God, is drawn to her like a moth to a flame, his body betraying his vows as he loses himself in her heat. Their love, forbidden and fierce, is a testament to the power of desire and the weakness of the flesh.
