How to Expose Possible Vampires (And Not Get Killed in the Process)

Edith Tusk is an introverted young woman working at a small coffee shop in Islington, London. She enjoys her privacy as she has problems trusting people... and has a dark secret. Having problems sleeping, Edith goes out at night to watch old horror movies at the local theater. One night, as she rides back home on her bike, she sees Leonard O'Doyle, a mysterious wealthy man who has just moved into the neighborhood hanging out with a much younger woman late at night, and when said woman screams in pain and fear and falls to his arms, a frighten Edith begins to fear that O'Doyle might be a vampire. These suspicions only grow stronger as she finds out that the woman has been found dead and that he seems to be allergic to garlic and sunlight. Fearing what he could do next, Edith starts following O'Doyle at night and discovers some other mysterious activities. She finds out that O'Doyle just bought a hotel nearby... and so, she decides that the best thing she can do is to expose his nature in front of everybody (as she doesn't think nobody will believe her word). She asks for the help of Cooper, a theater clerk who has a crush on her, and shares with him her plan - to put a piece of garlic in O'Doyle's breakfast the next time he goes to her coffee shop. Cooper agrees to help her... mostly because he is afraid she will get into trouble. Sure enough, Edith gets in trouble, but not in the way they could think of. As all of the events above happen, we also follow the track of Paul Coleman, a mysterious man who arrives searching for Edith... and who turns out to be her uncle and legal guardian. Paul reveals that Edith's true identity is actually "Amelia Coleman" and that she suffers from schizophrenia. As everyone begins doubting Edith, she decides to go all the way and expose O'Doyle whatever it takes. Together with Cooper, they track O'Doyle to his hotel. While Edith confronts him, the police arrive and arrest Edith... but not before she manages to throw some garlic pieces into O'Doyle's wine (who has become very uncomfortable at the sight of blood and garlic). As Edith and Cooper are taken away, O'Doyle's girlfriend (the girl Edith saw him bite) arrives at the hotel. Not only that. She ends up drinking O'Doyle's wine... and falls victim to the garlic. Yes! Both O'Doyle and his girlfriend are vampires... and O'Doyle reveals his true identity (and that his hotel is full of vampires), Edith, Cooper, Paul, and the police, have no other choice but to fight them together. Edith and her friends defeat O'Doyle and the vampires... even though O'Doyle manages to bite and transform Edith in the process. Wondering what to do, they decide to let Edith go. She makes peace with Paul and leaves together with Cooper.
