Emmanuelle is in search of a lost pleasure. She flies alone to Hong Kong, for a business trip. In this sensual world city, she multiplies experiences and meets Kei, a man who never ceases to elude her. With this film, Audrey Diwan gives us a free adaptation of Emmanuelle Arsan's novel and takes a feminine look at the intimate quest of the woman whose first name still evokes one of the most sulphurous characters in cinema.
