De geest van Vader Damien Karris, die 17 jaar geleden stierf, is overgenomen door een seriemoordenaar. De moordenaar misvormt priesters en dokters en gebruikt oude vrouwen als verdachten. Detective Kinderman gaat op onderzoek uit en zal een uitdrijver moeten zoeken om aan de moorden een eind te maken.
Nee, helaas is The Exorcist III nog niet beschikbaar op Netflix in Nederland.
