Exorcism in Christianity
Exorcism in Christianity is the practice of casting out demons from a person they are believed to have possessed. The person performing the exorcism, known as an exorcist, is often a member of the Christian Church, or an individual thought to be graced with special powers or skills. The exorcist may use prayers and religious material, such as set formulas, gestures, symbols, icons, amulets, etc. The exorcist often invokes God, Jesus and/or several different angels and archangels to intervene with the exorcism. A survey of Christian exorcists found that most exorcists believe that any mature Christian can perform an exorcism, not just members of clergy. Christian exorcists most commonly believe the authority given to them by the Father, Son, and Holy Spirit (the Trinity) is the source of their ability to cast out demons.
Alien Exorcism
Dr. Davide Piso is a courageous scientist who has been studying thousands of cases involving alien abductions with the aid of hypnosis. When the scientist decides to help Saturnia, a seductive teenager that believes herself to be an alien abductee and shows a clear attraction for him, he faces an insurmountable problem: once hypnotised, Saturnia cannot leave the trance condition anymore, hence giving manifestation to Hexabor of Ur, an alien entity coming from Mesopotamian ages. Hexabor considers himself a demi-god and wants to exploit a special human energy: the soul.
