Nadia does not want her widowed father Bramasto to marry Astria as she's sure that her new stepmother is not a good woman. Her suspicions are correct. After the marriage, Astria has an affair with Lukito, Bramasto’s black-magic-practicing brother. Astria then becomes involved in Satanic rituals and serves as Lukito’s servant. Her duty is to seduce men and then sacrifice them to Satan for Lukito’s benefit. Can Nadia stop them?
