Playing with Fire (1975)

Since the abductees in a series of kidnapping and extortion cases are all young girls, banker George de Saxx Georges de Saxe (Philippe Nuvale) demands ransom from his daughter Carolina Carolina (Anisa Alvina) in order to prevent her from being kidnapped (in fact, the kidnappers have asked him for ransom, but tied up the wrong person) Detective Laurent Laurent (Jean-Louis Trantinian) is hired to keep his daughter safe. Laurent suggested hiding Carolina in an apparently hidden but seemingly luxurious hotel, with Laurent, under the pseudonym Francis Francis, protected by makeup. But Carolina found herself in an extremely perverted den of fantasy worlds where kidnapped girls were forced to sell sex while waiting for their rich families to pay a ransom for the release of their beautiful daughters. It was here that Carolina found her father trying to change and seduce her, so Carolina and the cunning detective managed to escape and extort ransom from her father. This time, it's for real!
