By day, beautiful, pious nurse Mariana lives a pristine life as God’s devout servant, backing up her equally faithful best friend Michele in their church’s singing group, The Treasures of the Lord. But by night, Mariana and Michele lead an eerily masked, violent street mob, viciously attacking any woman they believe to be promiscuous – and not letting up until their victim accepts Jesus. But when Mariana is disfigured during an attack, she finds her social circle has little use for imperfection. When she takes a job at a dingy hospital, Mariana soon gets a taste of the secular world, exploring her sexuality and questioning her once-unshakeable faith. As intrusive thoughts take over and her church grows increasingly authoritarian, Mariana’s long-suppressed rage explodes, leading to a violent confrontation with the strictures of religion in this sleek, neon-hued thriller.
