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.
