Marie Laveau and the Vampire

Christian, a newly transformed vampire in order to save his life, is assigned to kill the Voodoo Queen Marie Laveau. His wife, the queen of the vampires (could be played by a man or a woman) is desperate for Marie’s murder. Christian has only been eating rats and must kill a priest whose blood is thrice as thick to survive. Marie is in a coma and half alive. Her holy blind daughter is trying to bring her back to life through prayer. In trying to kill her, Christian falls in love with Marie. His jealous queen wife suggests he kill Marie’s blind daughter. Will Christian kill her to save himself as a vampire and have a full life in the underworld? Or will the Queen, in murderous frustration, kill Marie?
