Financial difficulties will lead to the takeover of the Castejac company in Toulouse by the American group Fielding. Benoît Castejac goes to Paris to negotiate with Morrison, the group's representative. The latter instructs his director of public relations, Levêgue, to provide a call girl to the CEO of Toulouse: it is a question of making his stay more pleasant and easier the negotiation. Benoît meets Christine, who is introduced to him as Levêgue's niece, and falls in love with her. Back in Toulouse, he had to face a strike led by Bastide, the union delegate and one of the players of the rugby team led by Benoît. During a new stay in Pans, he learns the truth from Levêgue. He summons Christine, insults him, then he begs her to follow him. Christine laughs at him. In Toulouse, Françoise Castejac, jealous, decides to sleep with an envoy from Morrison, then to separate from Benoît. This one is alone, abandoned by all. One last hope: Christine.
