When her fiancé breaks off their engagement, Danielle leaves London and returns to her mother, Jenny, in Paris. With her business partner Benoît, Jenny runs what appears to be a respectable nightclub – it is in fact a place where wealthy men can buy the favours of attractive young women. Oblivious to her mother's professional and personal life, Danielle meets a handsome young man named Lucien, and falls in love with him – not realising that he is Jenny's lover...
