Night Junkies (2007)

If Giles Alderson doesn't guzzle human plasma once a night, he'll expire. But don't you dare call him a vampire. He's all right with sunlight, lives a fairly normal life, and prefers that you call his kind Night Junkies (2007), thank you very much. It's a disease like any other addiction, you see, and it leaves him feeling like enough of an outsider without all the name-calling. After bumping uglies with stripper Katia Winter, poor outsider Giles goes and nibbles her neck, bringing her inside his bloody little club. Lonesome no more! Then he feels bad about it, and he wants to help Katia deal with needing jugular juice for meals, so he sets out to make things right by promising to get her out from under her no-good boss, Jonathan Coyne. Jon, in turn, sics psycho blood-licker René Zagger on her. As if that weren't bad enough, skanks start turning up dead all over seedy London. Which of these bloody junkies is to blame?
