Sea of Souls - Season 3 Episode 5 : Succubus 2007

A young man is approached by lady who predicts his death, handing him a card bearing a drawing of a strange owl-like creature. He approaches the department, but Craig and Justine are sceptical. When he dies soon after his visit, the pair begin an investigation. Justine follows up the drawing, while Craig checks out a business card for an escort agency that was left in the man's jacket. When he tries to log on to the agency's website his computer crashes but shortly afterwards he is approached by a beautiful woman claiming to be from the agency, who begins to seduce him. Although she does not tell him who she is, she is the dead man's fiancee. Meanwhile Justine's investigations suggest that the man's death may have been the work of a succubus - a demon that seduces men to produce more succubi, killing those who do not successfully impregnate them. When Craig is hit by a mystery illness, it appears that he might be the succubus' next victim...
