Two orphan vampires (Les Deux Orphelines Vampires) follows Henriette and Louise (Isabelle Teboul and Alexandra Pic), two blind girls of unknown origin, raised in an orphanage by two adoring nuns. Little do the nuns know, each night as the sun goes down, their "little angels" acquire night vision (they "see blue"), as well as an appetite for blood and teenage mischief.

While growing up in rural Thailand, a young and beautiful orphan girl is taught the mysterious art of dark magic by her grandmother. When her grandmother falls sick, young Dau travels to Bangkok looking for work in order to earn enough money for medicine. She lands a job as an exotic dancer at a go-go club. Hesitant at first and ridiculed by the other dancers, circumstances force Dau to become an adult before her time and ultimately becomes the most popular and eerily seductive dancer at the club. Jealousies ensue and as her magic gets darker, the young girl gradually loses control as something abhorrently evil and wicked takes over.
