An affluent businessman Patrick Mariel must protect his wife Marianne and nineteen year old daughter Linda against Lorna,a predatory witch who once helped the family attain wealth and status and now demands Lorna's soul as her payment."Lorna the Exorcist" is a pretty unnerving and extremely sleazy horror movie made by Jesus Franco.There is plenty of sex(both lesbian and heterosexual) and lots of full-frontal nudity provided by Lina Romay,Jacqueline Laurent and Pamela Stanford.The action mostly takes place in modernist hotels and casinos.There is a strong fairly tale ambiance and plenty of perversity.The scene in which Lorna deflowers Linda by first having teenage girl suck from her breast and then by shattering her virginity with a dildo is truly unsettling as is the final descent of Linda into madness.8 exorcisms out of 10.
