Lively, flirtatious RHONDA FLEMING attends an art opening with her repressed roommate CRYSTAL TAYLOR in tow. She is drawn to the dark paintings, and she finally meets the mysterious artist, DR AKE VAN HORN, who is also the owner of The Hollow, the dance club where Rhonda works. With Drake is his assistant/girlfriend, NATOSHA. Watching from a distance is KEVIN MERDOCK, who we later find out to be a police officer.

Rhonda fantasizes about Drake, but he is more drawn to Crystal, and begins to speak about things from her past, particularly her father. Crystal becomes upset and runs away. Back at their apartment, as Rhonda prepares for work, Crystal mentions that she and Kevin - the same man who was eyeing Drake Van Horn - have broken up. After Rhonda leaves for The Hollow, Crystal heads over to Drake’s apartment, where she witnesses he and Natosha making love. While she is peeping through the window, Merdock approaches and questions her about Drake, whom he believes is involved in the death of a model named CARRIE WESTIN. Drake suddenly appears and escorts Crystal inside; after a little sweet-talking, he convinces her to model for him. They then make love, after which Crystal heads home and Drake heads to The Hollow.

Back at the apartment, Merdock stops by and again grills Crystal regarding her relationship with Drake Van Horn. She is at once surly and sexually aggressive – this is definitely not the Crystal that Merdock thought he knew. After they make love, Crystal gets dressed and leaves for The Hollow, despite Merdock’s adamant protests. Once there, she attentively watches Rhonda’s performance. Merdock follows, and questions Rhonda about Drake and Crystal; he learns that the two met only earlier that evening. Rhonda, just as perplexed as Merdock as to why Crystal would be acting differently and suddenly be so enamored with Drake, is unable to shed any light on the situation.

The next day, as Merdock hunkers down and attempts to crack the case, his boss, CAPTAIN THOMAS, dismisses the preliminary report on the mysterious Drake Van Horn as pure malarkey. Rhonda, worried since her roommate did not return home the night before, heads over to Drake’s apartment, where she encounters a very different Crystal. Finally, feeling pressure from the mayor’s office, Captain Thomas angrily orders Merdock off the case.

Undeterred, however, Merdock heads over to Rhonda’s apartment to search for more clues as to Drake’s evil doings. Surfing the Internet, Merdock determines that the only way to obtain the information he needs is to break into Drake’s residence and hack into his computer. Since Rhonda is a computer whiz, she comes with him. Once there, Merdock and Rhonda uncover incriminating and hard-to-believe evidence that Drake Van Horn may be responsible for dozens of otherworldly deaths. Events reach a stunning climax when Drake surprises the pair and, with Crystal’s life hanging in the balance, reveals his true identity.
