It is 1920s New York where we find Rosette Christopher, one of the most skilled exorcists in the world. As part of the Order of Magdalene, she travels to wherever demons are seeping through to this world and causing trouble so that she can exterminate them. With the power of God and the power of machine-gun fire, Sister Rosette and young Chrono will cleanse New York of its demonic problems. ~ Cammila Albertson, All Movie Guide
