Exorcism: The Battle for Young Minds, a 2018 BBC3 documentary in which Journalist Andrew Gold meets the famous exorcist Padre Manuel Acuña.
Acuña claims to be able to cure people of their possession by demons and evil spirits. He practices his cleansing rituals from his home city of Buenos Aires, Argentina, and has set-up the worlds first school for exorcists. These controversial techniques have apparently been successful in both ridding people of bad spirits and as an alternative form of medicine for people living in the area.
Is this man really helping people, or is he a deceitful shill? You decide.
