From Dusk Til Porn[2004]

A seething mass of sex shops and nightclubs populated by the seedy underbelly of society: the desperate, the weak and the unloved. Lurking undetected in this den of iniquity is an even greater evil. The Vampire Jon Harker has had a bad day at work, but it's about to get a lot worse. Recounted from the police station, this tragic love story is told to two police inspectors, DI Topperov and DI Nurmi.
