Forever Knight (1992)

S3E20 Francesca

Nick and Tracy are both haunted by the horrific "kiss" murders, where victims are found completely drained of blood. Nick suspects that these killings bear the mark of Francesca, a vampire from his past. But she’s supposed to be dead—could she have returned? Meanwhile, Tracy grapples with overwhelming feelings of Deja Vu that she can't shake off. When a psychotherapist approaches them with details about a patient she's been treating, it seems they've pinpointed the killer. Yet, they must decide whether they're facing a twisted murderer or the vengeful spirit of Francesca. If it is indeed her, Nick’s life could be at stake.
