Ricardo Bertini makes and sell sexy underwear. He arranges with Lisa to help him launch his new range in France. It isn't clear what relation Jean is to Lisa, perhaps a brother. Lisa drives Jean to the airport to catch his flight and picks up Ricardo, who has been chattin up another passenger (XNK0531), to come to stay at her place. Ricardo seduces her maids (one of whom is Claire Lenoir, the other XNK0532) and a blonde (XNK0534) who shows him a property, but fails with Lisa, as she is more interested in Minouche. There is also a fantasy sequence as he examines a men's mag while sitting in a deckchair. Two females, one in white and one in black stockings, bend through holes in a wall so that Ricardo can see only their legs and behinds. He takes them from behind one after the other and then four more holes appear through which breasts project for him to lick. When we cut back to reality a maid (Claire Lenoir) is giving him a blowjob. Meanwhile Alban gets a massage from an exotic looking brunette (XNK0533) and a little later has sex with Guia Lauri, seemingly while watching Der Frauenarzt vom Place Pigalle on TV. Lisa arranges for half a dozen models (Cathy Stewart, Dominique Saint Clair, Isabelle Brell, XNK0535, XNK0536, XNK0537 and XNK0538) to parade his stuff in front of the pool and later he picks up two of them in a bar (Dominique Saint Clair and Isabelle Brell). They distract him from chatting up the barmaid (XNK0540).
One of the maids (Claire Lenoir) has visited a nightclub (Emmanuelle Parèze makes a fleeting appearance here, in gold trousers) where Nicole Segaud then hatches a plot to kidnap Ricardo with the help of Dominique Aveline and Jean-Pierre Armand. She takes advantage of him in a dungeon and then Jean-Pierre takes advantage of her Ricardo can't pay the ransom, but Lisa's father (Oliver Mathot) can. The kidnappers pick up the money and dump Ricardo near to Lisa's house. He staggers in with his arms handcuffed behind him to find Alban has returned. Alban releases him and then we see Ricardo marrying Lisa and discovering all his new relations - a ready-made family in fact - while Alban drives away in his sports car with two girls.
