The teenager Melissa (Agnès Spaak) travels from her small town in Austria with the Spanish Juan Manuel (José Rubio), who flirts with her, to the creepy castle of her uncle Dr. Conrad Jekyll (Marcelo Arroita- Jáuregui) in Holfen to spend Christmas with him and her aunt Inglud (Luisa Sala). Melissa's father Andros (Hugh White) has mysteriously died at the house of his brother Conrad sometime ago. Now she has just reached majority and Conrad intends to transfer the inheritance to her. Melissa is received by the servant Ciceron (Manuel Guitián) and she meets the strange Inglud. Then she meets Conrad in his laboratory, where he secretly carries out a sinister experiment. Melissa wants to get information about the death of her father but she is ignored by Conrad and Inglud. In the past, Andros and Inglud had a love affair and Conrad surprised them and killed Andros. Now, Conrad has turned Andros into a killer zombie controlled by ultrasonic radio wave and uses him to kill women with easy life. Inspector Klein (Pastor Serrador) is investigating the murders but has no clue. Will Melissa find the truth about her father?
"El secreto del Dr. Orloff" is one of the best movies by Jess Franco in the earlier stage of his uneven filmography. The story is simple but makes sense; the acting is not bad but unfortunately Marcelo Arroita- Jáuregui is weak for a villain; and the black and white cinematography and the camera angles are top-notch. The music score by Daniel White is perfect for the atmosphere of this film. My vote is six.
Title (Brazil): "As Amantes do Dr. Jekyll" ("The Mistresses of the Dr. Jejyll")
