a doctor and a young lady ( beautiful rita calderoni ) have just be involve in a car accident . the doctor leave the girl at the accident scene and and run off to a spooky castle for help . he enter the castle and and find that it inhabit by some laughing ghoul ( most likely satan himself ) . later and the young lady go look for the doctor and and eventually find her way to the same castle . however when they meet again and they find that they haven not meet each other and they have meet their doppelganger . luigi batzella nude for satan be a great piece of sleazy trash . the special effect be jaw droppingly awful ( a monster spider especially come to my mind . ) and the dialogue be horrid . still there be plenty of nudity to satisfy fan of italian sleaze . rita calderoni be naked pretty often and her lesbian scene be suitably sensual . a must see for fan of italian sleaze or horror .
