Vampire Warriors (2010)

Ar spends her days walking around hunting down bad vampires, while Max and her good vampire friends hang around town aimlessly, complaining about how bored they are. That all changes with the arrival of Mung (Yuen Wah), a vampire who kills other vampires to make himself more powerful (don't they always?). When Ar realizes that Mung's dragging her sister (Law regular Pinky Cheung) with him, she joins forces with the vegetarian vampires to fight their common enemy.
