Detectives Olivia Benson and Eliot Stabler find a woman bleeding from the neck and nearly dead. The woman dies before they reach the hospital, and soon the investigation leads them to the frontman of the death metal band Vampyre Sacrifyce. He bites girls, steals blood from the local blood bank and sings about violence to women all in the name of his strange, vampiric lifestyle. The singer claims he was nowhere near the scene of the crime, and soon a lesbian rights group led by Babs Duffy gets involved, claiming the victim's death was a result of police neglect. However, when more women from Babs's group are attacked, it becomes clear that the victim's case wasn't an isolated incident and that someone out there has a larger plan to bring the group down.

When security cameras record footage of a woman being abducted, it isn't long before Captain Donald Cragen and the SVU squad find the woman dead in the basement. Detective John Munch recalls a similar case from twenty years before, sending Detectives Olivia Benson and Eliot Stabler to Sing Sing to speak to the culprit, who begs them to reopen his case and prove his innocence. As strange similarities between the two cases begin to arise, Benson and Stabler face fierce opposition from Ingrid Block, the pit bull attorney for the main suspect who will do whatever it takes to prove her client's innocence. Ultimately, it falls on DA Jack McCoy to decide whether or not the ruthless lengths to which Block went to defend her client constituted a crime itself.
