In the RTF studios, Christine Beauval, the channel's star newsreader, is assaulted. A few days before, thanks to her friend Éric Jauffret, minister of information, her husband Pierre had been made boss of Mondovision.

Christine remembers a machine operator who once hassled her and decides to go and see him.

Christine and Philippe Lefebvre are arrested for Marcel Lindet's murder. Darnet takes the chance to sideline the newsreader in favor of young, beautiful Isabelle. Christine, who suspects her husband of cheating on her, moves into a hotel.

After being sacked, Christine manages to get on air to speak directly to viewers. Recruited by the OAS, a terrorist group, Jean-Claude's first mission is to attack a restaurant.

Pierre Beauval and Philippe Lefebvre realize Christine was with Jauffret at the site of the attack; Pierre and Philippe decide to work together to find Christine.

The Beauvals are terrified for their daughter's disappearance, but they believed she ran away; Pierre needs to leave Britain; Christine looks for Colette, to no avail.
