Plot
In 1940, film star Viviane Denvert sits in the audience of a premiere of her new movie and notices a man who keeps staring at her. She is disturbed, and when the film is over and the audience has finished praising her, she rushes home, discovering she is pursued by the same man. He chases her into her apartment.
An hour later, Frédéric Auger, a young writer, receives a call from Viviane, who was his childhood crush. Viviane, who has long used Frédéric's devotion, asks him to come to her apartment immediately.
