MULDER IS INTRIGUED BY A BEAUTIFUL SUSPECT AS HE DELVES INTO A SERIES OF MURDERS WITH VAMPIRE-LIKE CHARACTERISTICS.
A businessman is killed in his own hot tub by a trio who drain his body of blood. Mulder, now without Scully to help him, tracks one suspect to a blood bank, where he finds the man drinking blood. Mulder arrests him but thinks his claims of vampirism are a psychotic delusion; he is astonished when his suspect dies as soon as he is touched by sunlight. Now determined to know if vampires really exist, Mulder plunges into a dark and dangerous underworld where sex, murder and blood intermingle in trendy nightclubs. His search is complicated by his involvement with an alluring suspect, who is linked to the unholy trinity of killers by ties of blood and desire.
