A mother reports her eighteen year old daughter missing when she receives a horribly graphic and sexual message on her answering machine about her daughter. Stabler and Benson attempt to track her down and in the midst of the investigation, a psychic (who the mother believes to be gifted) claims to see visions of the girl. This psychic turns out to be the killer -- one who is obsessed with female virgins -- and this girl is only one of twelve who he raped and murdered.
