When a series of vampire-style murders plague L.A., immortal investigator Mick St. John (O'Loughlin) sets out to find the culprits and re-connects with a woman, Internet reporter Beth Turner (Myles), from his past at a crime scene, on the series premiere of MOONLIGHT, Friday, Sept. 28 (9:00-10:00 PM, ET/PT) on the CBS Television Network.

RECAP:
At the crime scene of a murdered college student, Mick St. John meets internet reporter Beth Turner. Though two puncture wounds to the neck make it appear that the young coed was killed by vampires, Mick knows that this wasn’t the case, because he detects no smell of vampire on her. Together, Mick and Beth find the girl's professor, a self-proclaimed vampire who uses his knowledge of vampire lore to seduce college coeds. A second killing brings them no closer to an answer. Beth goes undercover to see what else she can find out about the enigmatic professor, and finds herself in danger. Fortunately, Mick comes to her rescue, using his vampire strength to overcome the true villain.
