In Spain, in a tall castle, or Abby, lived the Vasquez family, made up of Julia Vasquez, the mother, Amy Vasquez, the teenage daughter and older sister of Henry Vasquez, who became possessed by a demon named Asmodeus, a prince of demons. Father Gabriele Amorth, an Italian exorcist, and his assistant from the local church Father Tomas Esquibel, were trying to exorcise the demon from the young boy in his bedroom. Asmodeus wanted Father Gabriele’s body to destroy the living world.
