Detective Dallas Wilder, DA Joe Hardick and assistant DA Rachel Steele has been trying to break up a satanic cult in the area. Now the remnants of that cult are hitting back. They have summoned a Succubus to possess Rachel and use her body as a means to seduce and destroy her colleagues. Dallas is the first victim. After being drawn into an erotic lesbian encounter with Rachel, she is cynically killed. In Joe's case, Rachel gets him to act out an assault on her, and then calls the police on him. Finally, the Succubus departs Rachel's body, leaving it lifeless. The cult's revenge is complete.
