Under the dim neon lights, two mysterious women live in the cold and humid city: Clara (Gemma Arterton) and Eleanor (Saoirse Ronan). They call each other sisters, stick to the small space in a corner of the city, and don't want to attract the attention of others. For the vampires, this may be the best way.
