Trama

A young woman is kidnapped and forced to participate in an orgy. Later, she is presented to her own father in another orgy.

Susan Hemingway hooks up with a guy at a discotheque, has unwilling sex (Brigitte Lahaie joins in on the action) and is drugged and sold off to a "deluxe bordello" where a bunch of dirty, moaning girls are kept in a constant state of excitement by some sort of sex-gas that is pumped into their living quarters.—oraklon

Lorna and her lover Tom abduct Jenny, a 16-year-old virgin from a disco in Paris. Lorna calls her accomplice Maria - a procurer for a sex slave ring that involves Marcos, a sea merchant captain. A deal is agreed on. Lorna inspects Jenny's virginity before sending her to the white slavers. Jenny, Sylvia, and a third girl are taken from the cargo ship to a yacht, nude, under lose shirts; two young men - a white and a black - are waiting for them to transport them in a black car to a luxury villa nearby. From a public phone in Lisbon (Portugal), Maria calls Mr. Goldstone in America, and ask US$5,000,000 to return his daughter Jenny intact. He agrees to pay, and not to call the police. Yet, the couple make an offer of the girl to another rich man, Robert. From the transatlantic cruiser Kungsholm IV moored in Lisbon's dockyard, a number of passengers come ashore, including Lorna and Tom. The least pressed person is a cigar smoking man with a cap. However, as soon as the couple takes a taxi for a nightclub, the man with a cap hastes to follow them in another taxi.

Six girl slaves are seen naked, except for black nylons, on two beds and two mattresses on the floor; they are moaning and squirming alone, and then on top of each other, under the effect of a sexual stimulating gas that is being injected into the room via a pipe in the ceiling. That makes the girls say aloud that they are burning all over. The black young man informs Madame that Sylvia is getting mad; Madame tells him to appease her sexual desire after putting her back to her cell, but changes her mind and tells him to do it there, on her bed - so she and her companion can watch. The black man couples with Sylvia (now in black knee boots) while Madame and her lover watch and masturbate.

Lorna and Tom arrive at the nightclub, and walk down to the basement. They wish to see Madame Flora on the part of Mr. Goldstone, but the black man tells them that she is occupied. Soon, the man with a cap joins them in the basement, where nude girls are drinking or having sex on a stage. When the man in a white vest is trying to find out about Jenny from one of the stoned girls, the black man interrupts their talk. He takes them to Flora, but in the corridor he and his white partner knock out the couple. The black man returns to the room, and asks the man with the cap if he wants a drink, or to just watch the show. He refuses both, and leaves. The couple is tied up, sexually molested, and then dropped on the road (off camera). Mr. Goldstone calls Flora, angry, because of what happened to the couple. He warns her that he is coming next day himself to see her.

Next morning, Mr. Goldstone comes to land from the same cruise ship, and takes a black car with his driver and a male secretary - under the attentive eye of the man with a cap, at the harbor promenade in Cascais by the Fortress Nossa Senhora da Luz.

Mr. Goldstone arrives at Flora's luxury house, overlooking Boca do Inferno (literally, hell's mouth) - followed from a distance by the man with a cap. The rich man reproaches Flora for what she has done, but she appeases him with caresses and by naming the $20 million dollars she has gained for him. He seems to be ready to settle with her in California, but then he tells her of his big worry: his daughter has been kidnapped a month ago, and he has no news of her.

Lorna and Tom break into Flora's house - watched from a distance by the man with a cap. But again they are captured by Flora's henchmen. Meanwhile, Flora has engaged in foreplay with Goldstone and her white henchman, who leaves the bedroom to bring in the new virgin for Mr. Goldstone. When she's shoved into the room, surprise. Jenny sees her father naked, hugging and kissing Flora. He is both glad to find her, and worried about what happened before. Flora tells him that she had bought her from a couple, but they are now "hiding" at the bottom of the sea. He feels relieved. A woman's cry off camera signifies that Goldstone's staff may have disposed of Flora definitively.

Goldstone and Jenny get aboard his car, and the car leaves. They talk, the father-daughter relationship is re-established on better grounds, and she's ready not to escape from home again. Let bygones be bygones. The car comes to a sudden halt. The driver is the man with the cap, still chomping his cigar. He presents himself as federal agent Al Pereira, and he says he's taking them to the airport and back to the United States, so that Goldstone may be brought to justice.
